What Is Blood Blazon?
Red blood cells (chosen erythrocytes) have a type of antigen on their surface. Composed of sugar molecules, these antigens are called agglutinogens. There are 2 types of agglutinogens: type A and type B. The type of antigen on the surface of your reddish claret cells determines your blood type.
There are iv basic blood types, made up from combinations of the type A and type B antigens.
Type A: The red blood cells take the blazon A agglutinogen.
Type B: The ruby-red blood cells have the type B agglutinogen.
Type AB: The red claret cells have both type A and type B agglutinogens.
Type O: The red claret cells do not have any agglutinogens at all.
There is another poly peptide (called Rh factor) that is sometimes found on ruddy blood cells. If a person has Rh factor, their blood type is called "Rh positive." An individual lacking this protein is called "Rh negative." Combined with the ABO blood types described higher up, a person may be A+, A-, B+, B-, AB+, AB-, O+, or O-.
Blood Types Around the Earth
Blood Group Poll
Claret Types Effectually the Globe
Blood types vary depending on the geographical region: Scandinavians accept a loftier probability of carrying the A blood type, while those indigenous to cardinal Asia are more likely to carry the B blood type. The O blood type is the most common blood type around the world.
According to the National Center for Biotechnology Information (a molecular biological science resource funded by the government), the breakdown of blood type past region is:
Claret Type A: Cardinal and Eastern Europe
The A blood group is common in primal Europe. Nearly one-half the population in Denmark, Norway, Austria, and the Ukraine take this blood type. This blood type is besides constitute in high levels amid modest, unrelated groups of people. In Montana, 80% of the Blackfoot tribe has the A blood group.
Blood Blazon B: Asia
The B blood type is rare in Europe (nearly 10% of the population), but adequately common in Asia. Nearly 25% of the Chinese population demonstrates this blood type. This blood type is as well fairly common in Bharat and other Central Asian countries.

Blood Type AB: Asia
The AB blood type is the rarest of all. Information technology is found in up to 10% of the population in Nippon, Korea, and China, just is extremely rare in other regions.
Blood Type O: The Americas
The O blood type is the most mutual around the world, and is carried by about 100% of those living in South America. It is the most common claret type amidst Australian Aborigines, Celts, those living in Western Europe, and in the U.s.a..
Rh Gene
The bulk of people in whatever geographical region are Rh positive. Caucasians are the most likely to be Rh negative, with approximately 17% of blood donors demonstrating a lack of this poly peptide. Native Americans are the next highest proportion of the population to examination as Rh negative: approximately 10% of donors from this population lack this protein.
Coconut Juice Blood Transfusions in World War Two
As Earth War II raged through the Pacific, blood products were in short supply. In emergency situations, Japanese and British medics would resort to coconut h2o. Coconut water (the juice within a young coconut, not "milk" which is made from grinding up the meat of the fruit) has fewer electrolytes than blood plasma, merely it is sterile and works in a similar style to a saline IV drip. In a compression, coconut water is tolerated fairly well past humans. In fact, coconut water preserves teeth improve than milk - something to keep in mind the next time a tooth gets accidentally knocked out!
The History of Blood Transfusions
In the 19th century, no one understood that people had different blood types. Blood transfusions frequently resulted in death, equally the receivers allowed system would attack the foreign, unmatched blood that was transfused.
The history of claret transfusion goes all the way back to the 1600'south, when William Harvey discovered the circulatory organization. By 1658, January Swammerdam was viewing cherry-red blood cells through a microscope. The very outset transfusions occurred in dogs, as the English md Richard Lower demonstrated that a dog could be kept live past transfusing blood from other dogs.
Unfortunately, the motion to human transfusion was quite tricky. Equally there was no agreement of blood groups, blood transfusions were extremely risky. Sometimes they were successful: in 1818 James Blundell managed to achieve the start successful human claret transfusion, and saved a woman hemorrhaging from childbirth. Other people, nevertheless, simply went into shock and died after blood transfusions.
Some scientists attempted to prevent the adverse reactions to blood transfusions by transfusing blood substitutes. The transfusion of moo-cow's milk was attempted in 1854 in Canada, during a cholera epidemic. Drs. Bovell and Edwin Hodder started intravenous transfusions of milk in the belief that the fatty molecules in milk could exist transformed into white blood cells, and that white blood cells were an immature version of red claret cells. This belief was erroneous, of form, merely they had success with 1 sick human who responded favorably to the transfusions. Two other patients, however, died after milk was transfused into their veins.
These experiments were discontinued in Canada shortly after the cholera epidemic, but were revived in New York City a few years afterward. Using goat'due south milk this time, Dr. Joseph Howe transfused patients suffering from concluding tuberculosis. The patients all demonstrated nystagmus (shaking eye movements) and breast hurting, and all of the patients died a few hours afterward transfusion.
Despite the lack of obvious benefit, milk transfusions continued in the belatedly 1880'southward, equally the apply of blood was discouraged since information technology had a tendency to coagulate. As more patients died from milk transfusions, the practice brutal out of favor. In the 1880's, isotonic saline solution was invented, and the use of milk fell entirely out of favor in favor of the new, prophylactic saline solution. The revival of blood transfusions would have to wait for the 20th century, when a new era of microbiology ushered in the agreement of various blood groups and compatibility.
In 1901, an Austrian doctor named Karl Landsteiner recognized the three basic blood groups – blood was commencement cross matched in 1907. Blood storage was nevertheless a problem during the early days of blood transfusion – while the compatibility issues had been resolved, blood still had a tendency to jell during storage. Anticoagulants like sodium citrate were developed in the year 1914, allowing blood storage for an extended period of time. The discovery of Rh gene in 1940 allowed doctors to completely understand the compatibility issues amidst claret donors and recipients, and the American regime started its beginning national blood collection program shortly thereafter.
Claret Typing Video
Blood Blazon Tests and Claret Transfusions
A traumatic car blow has occurred, and a severely injured patient is rushed to the emergency room. Equally the patient lies bleeding, doctors scurry to take a sample of the patient's blood and take it sent away to be typed and cross-matched.
In the laboratory, a technician applies the claret to a special menu, which contains antibodies to the A and B claret groups. If the patient's blood clumps around the A antibiotic, this means they have the B antigen and information technology is attacking the A antibody. If the patient's claret clumps around the B antibiotic, then the patient has the A blood blazon. If the patient'southward claret clumps effectually both the A and the B antibody, they have the O blood type, and if the patient's claret doesn't react to either the A or B antibodies, then he or she has the AB blood blazon.
In the case of our patient, the blood clumps around both the A and the B antibodies. The patient has the O claret type. An Rh test is also performed, and our patient is positive for this protein.
Equally determined by this exam, the patient needs a transfusion of type O+ or O- claret. The claret bank releases type O+ blood for use, and the patient is then cross-matched to be certain there are no adverse reactions.
The sample of the O+ claret is taken from the blood depository financial institution and mixed with the patient'due south blood in a exam tube. The sample is watched for whatever adverse reaction, and if no clumping is noted, the claret is prophylactic for the patient to use. The sample demonstrates no reaction with our patient's blood, and then the bag of donated, O+ blood is rushed down to the waiting patient. Equally blood is transfused, the patient's vital signs meliorate.
Blood Types and Compatibility
The AB+ blood blazon is known equally the Universal Receiver: an individual with this claret blazon can receive any other blood type without reaction.
The AB- blood type may receive claret types A-, B-, or O-; whatsoever transfused blood must be Rh negative to avoid reaction.
The A+ blood type may receive blood types A+, A- , O+, or O-.
The A- blood type may receive claret types A- and O-.
The B+ blood type may receive blood types B+, B-, O+, or O-.
The B- blood type may receive blood types B- or O-.
The O+ blood type may receive blood types O+ or O-.
The O- blood blazon may only receive the O- blood type. People with O- blood are known every bit Universal Donors, as their blood will non crusade a reaction with whatever other claret type when donated, since the blood lacks all surface antigens and will non provoke an immune system attack in the receiver.
Blood Compatibility and Rh Factor
Claret Type Complications: Rh Gene in Pregnant Women
For most people, blood blazon is of lilliputian consequence in life. Sometimes, however, a adult female is Rh negative and becomes meaning with a baby who is Rh positive. If this is the start pregnancy, the baby is ordinarily fine because the mother's blood doesn't mix with the baby'due south during the gestational period. Sometimes, yet, the baby'due south and mother's claret mixes during delivery. The mother's immune arrangement then begins to mount a defence force against the foreign protein.
When the mother gets pregnant for the 2nd time with an Rh positive baby, the risks are much higher. In this instance, the mother'south allowed arrangement may react to the strange Rh protein carried by the infant. When this happens, the mother's immune system attacks the baby'south ruby blood cells, causing them to rupture. The babe develops a class of hemolytic anemia, which can be fatal.
To prevent impairment to the infant, the female parent can exist given injections of Rh immune-globulin. The Rh allowed globulin is an antibody for the Rh factor: if any of the infant'southward blood has made its way into the mother's system, the Rh immune-globulin binds to the baby's blood cells. These "borrowed" antibodies volition prevent the mother's immune system from producing her ain.
If a mother demonstrates high levels of Rh antibodies in her blood system, the baby is carefully monitored. If the infant shows signs of distress, a procedure known as an commutation transfusion is sometimes performed to replenish the infant's blood supply.
Claret Type Inheritance
Inheritance patterns of the ABO blood groups - A and B are codominant, so those who inherit type A and type B alleles will accept type AB claret. Those with types AO or BO will exist type A or B, respectively.

Blood Blazon Genetics
Blood types A and B are co-dominant, so if the father has claret type AA and the mother has blood type BB, the child will have a blood type of AB.
Blood Type O is recessive, so a child will only have this blood blazon if he or she gets ii O blood type genes from his or her parents. If both parents are blood blazon O, all of the children in the family will accept the O blood blazon. Another way this can happen is if the parents are heterozygous for the O allele: this means the female parent may exist claret type A, but her genotype (the genes she carries) are really AO. In this example, she expresses the A blood antigen, but she likewise has a gene for the O claret type. If she marries another heterozygote AO carrier, there is a adventure that ane of their children would inherit both O genes and then take the O blood type. The hazard of this family unit having a kid with the O blood type is 25% - in that location is a 50% chance they would have a kid with the AO genotype (which would have the A blood type) and a 25% chance they would have a child with the AA genotype (A blood blazon).
Blood type A is dominant over blood blazon O, so anyone who has one A gene will accept the A blood type, even if they carry one blazon O cistron.
Blood type B is dominant over claret blazon O, so anyone who has 1 B gene will have the B blood type, even if they carry one blazon O gene.
Rh factor is ascendant, then a parents who are have two alleles for Rh factor volition have children who are Rh positive. If the parents are heterozygous (having one Rh factor allele and ane Rh negative allele), they take a 25% chance of having an Rh negative child. If both parents are Rh negative, all of their children volition exist Rh negative.
Questions & Answers
Question: What pct of African Americans take blazon A claret?
Answer: According to the American Red Cross, approximately 26% of African Americans have type A blood. Of this percentage, 24% are A+ and 2% are A-.
Question: I take type O, RH positive so are my parents the same type?
Answer: Your parents may non take the same blood type y'all do. The O blood type is double-recessive, so your parents could be type A, type B, or type O and even so take a child with an O blood type.
Question: My mum, my sister and myself have A- blood, but my younger sister has AB. What claret blazon would our father have had?
Answer: Your father likely had Type BO blood. If your mother is blazon AA and your father is blazon BO, then the combinations would have resulted in a l% risk of having type A claret (AO genotype, just O is recessive) and a fifty% take chances of having type AB claret (the A and B types are co-dominant and will express themselves at the same time).
Question: I recently discovered through our family'due south research that all of the men on my father's side all had/have O- claret. I'm the son of a genetically identical twin and the other twin had twin boys with O+ blood. Offset can y'all explain why all of the men in my lineage have O-blood? And why are my aunt's son O+? My parents were also O-.
Answer: The negative Rh factor is recessive, so it is likely that your mother and father were both negative. Your uncle was an identical twin to your father, which means he was also negative. If your uncle married a woman with a positive factor, then in that location would be a fifty% chance of each child having a positive cistron at nascency, and a fifty% chance of having a negative cistron. The positive factor is dominant.
Question: How did I get an AB+ claret blazon?
Answer: Blood types A and B are co-ascendant, so if you lot inherit the A blood type from 1 parent and the B claret type from another parent, information technology is quite possible to accept type AB blood. The positive Rh factor is adequately mutual and is inherited separately from the AB blazon.
Question: Can a infant get the Rh negative claret blazon from a grandparent if both parents are positive?
Answer: The Rhesus gene is a recessive trait, and so a baby can inherit a negative Rh cistron if both parents are positive heterozygotes. In this scenario, we could suppose that a grandparent is Rh negative, but has a husband who is Rh positive. Their kid would likely exist Rh positive, simply would bear the gene for a negative rhesus gene (this is called a heterozygote - they comport the factor merely do not limited the trait). If this kid grew up and married another heterozygote, they would have a 25% probability of having a babe that is Rh negative, a 50% chance of having a child who is Rh positive and a carrier of the negative gene, and a 25% gamble of having a child who is positive and does not carry the negative cistron at all.
Question: My mom is O positive and my begetter was A positive, but I'thousand O negative, how is this possible?
Answer: This would be possible as type O is recessive, forth with the negative blood type. In this case, your mother would be O+O- and your father would be A+O-. While they demonstrate only the dominant form of each cistron (the positive Rhesus factor for both and the A claret blazon for your father), each one carries the O- gene and passed it on to you.
Question: My blood type is AO, and my children'south begetter is type O. How does my son take blazon AB?
Answer: I cannot explain how your child has type AB blood if his biological father has type O blood. Blazon O claret is double recessive. With a mother having AO blood and the father having OO blood, the possible combinations are AO, AO, OO, and OO. Your children would take a l% chance of having type A blood (the AO genetic blazon) and a 50% chance of having blazon O blood (the OO genetic type).
Question: What does it mean if my mother is RH- blood blazon and I'thousand O- blood type? What does this say about me?
Reply: Your mother'due south Rh cistron is negative, and then is yours! Yous don't give your mother'due south blood type, which is typed as a alphabetic character (A, AB, B, or O). The O blood type is recessive, so for someone to have the O blood blazon, they need two recessive "O" genes. Your mother could exist A, B, or O since many people who are type A or B carry an O gene (A and B are ascendant over O).
Question: I take A+ blood. My father was of Sicilian descent. My female parent was of German and Irish gaelic descent. Is A+ blood type uniform with my genealogy?
Answer: Yes, the A blood type is compatible with your ancestry. The A claret type is dominant and is found throughout Europe.
Question: My dad is Syrian with type O+ and my mom is African mixed with Indian and carries B+ however my sister and I carry type AB+. How is that possible?
Answer: Information technology would not be theoretically possible for a parents with type O and blazon B to produce children with blazon AB blood.
Question: I accept AB blood. My father's side all have O claret and my female parent'southward side all take O blood. Is it possible for two type O parents to have a child with blood type AB?
Answer: It is highly unlikely that 2 parents with Blazon O blood would produce a child with an AB blood type. Since the O claret blazon is double recessive, your parents each take OO and OO, which would effect in all children having type O blood. To obtain Type AB, one parent must take Type A, B, or AB blood and the other parent must also take blazon A, B, or AB claret.
Question: In what office of the world is Rh negative blood type most ordinarily found?
Reply: Australia has the highest percentage of Rh negative blood, with approximately nineteen% of the population demonstrating a negative gene. The Basque population in Spain has the highest percentage of Rh negative blood as an ethnic group, with 21-43% of Basque people demonstrating the negative factor (dependent on location).
Question: I have blood type B+ only my mother is from Germany. Is my blood type uniform with my genealogy?
Answer: Yes, it is possible to have type B+ blood with German language ancestry. There has been a lot of migration and movement throughout man history, and currently xi% of Germans have type B blood (9% have type B+ and 2% have type B-).
Question: If I am AB+ what were my parents?
Answer: Your parents might both exist type AB, one parent might be type AB and the other might exist type A, one parent might be blazon AB and the other type B, or you may have one parent that is type A and ane parent that is type B. Whatever of these combinations could produce a child that is type AB.
For the + Rh gene, both of your parents are Rh positive.
Question: What is the most common blood type in Sweden?
Answer: The most common blood type in Sweden is A+. Approximately 37% of the population has this blood type. The second most mutual blood type in Sweden is O+.
Question: I am an A+ claret blazon and I desire to go married. Which claret group should I ally?
Answer: You should non consider someone else'south claret type when you are because a future spouse. Blood blazon has no bearing on health or general compatibility.
Question: Why is Africa excluded from your article'south world analysis?
Answer: Africa is not excluded from this world analysis. The listing of blood type percentages merely lists the continent where each blood type is the most common. In this synopsis, Blazon A has the highest prevalence in Europe and Central Europe, Type O has the highest prevalence in the Americas, Blazon B and Type AB accept the highest prevalence in Asia.
Type O+ blood is the most common beyond the continent of Africa, but it does not take the highest prevalence in the earth of this blood blazon. 45% of South Africans have Type O claret, but this is non the highest prevalence (virtually 100% of South Americans have Type O blood). In brusque, the blood types beyond the continent of Africa are varied and it does not take the highest prevalence of whatsoever ane blood blazon.
Question: What is the youngest blazon of blood in humans?
Reply: According to the BBC, type AB is the nearly recent blood type in humans. While the O blood type is universally compatible, information technology is not likely to be the oldest claret type among humans. Both the A and B types may become O with a few mutations, so it is likely that A is the oldest, followed by O or B. There are competing theories on blood blazon and evolution. Each type varies by geographical region and ethnicity.
Question: My mom, dad, and sister have blazon O negative blood, only I accept a positive Rh factor., is this possible?
Answer: In general, the negative Rh factor is a double recessive cistron. If both of your biological parents are Rh-negative, and then you should also have a negative Rh factor.
Question: You said claret type A is dominant over O. I'm A- and my son is O+. I don't know what claret type his dad is, though. Exercise you lot know if my son is recessive rh-? Does this mean I am recessive rh+?
Answer: The positive Rh trait is always ascendant. Since you are A-, that means you accept two Rh negative alleles. Your son's begetter is near probable blazon O+ blood. You carry an O allele (so your genotype would be A- O-). In your case, the O is recessive and so you just brandish the physical characteristic of the A blood blazon. Your son inherited one re-create of the O gene from you and from his father. He inherited one negative Rh gene gene from you and one positive Rh cistron from his begetter, and so he displays the Rh positive phenotype (since the positive factor is ascendant).
Question: Can an A- person e'er have ii parents each with O+ blood type?
Reply: A person may inherit a negative Rh factor from two parents with a positive factor, if each parent is heterozygous for this trait. If the mother is +/- and the father is +/-, each will accept a phenotype (physical characteristic) of having a positive Rh factor while all the same carrying the negative Rh factor gene. Each child would take a 25% chance of inheriting both Rh - alleles and demonstrating that phenotype. Two parents with type O blood, however, would not have a biological child with blazon A blood. Type O blood is double recessive.
Question: What percentage of African Americans accept type B blood?
Reply: 18% of African Americans have type B+ blood, and 1% have B-. Excluding Rh gene, 19% of African Americans bear this blood type.
Question: My wife and I have are A/B-, what blood type will our child take?
Answer: Your child's rH factor will exist negative, as you lot and your wife are both negative for this factor. The child'southward blood type will depend on which genes they obtain. The A and B blood types are co-dominant. Your child may obtain the A gene from both parents (25% gamble of A- blood type), the B gene from both parents (25% chance of B- phenotype), or 1 of each (l% chance of AB-).
Question: I have a B+ claret blazon. My girl is O+ and my son is B+. My husband forgot his blood type. Can you effigy what claret type my husband is?
Respond: The only mode to actually know what blood blazon your married man is would be to have information technology typed. The only thing we know for certain is that you and your husband each carry a cistron for the O blood type, which is recessive. You likely carry one factor for B and one for O (B is dominant so your blood type is B). Your hubby could be AO (A blood blazon), BO (B blood type), or OO (O claret blazon). Your daughter would take inherited 1 O allele from each of you, resulting in her double-recessive claret type. If your husband would like to know his blood blazon, he should have it typed, every bit information technology is impossible to know from your children's profiles.
Question: Tin can a person have blood type ABO positive ?
Answer: A person could exist type AB or type O, but not blazon ABO. If a person carried the genotype for type AO or type BO, they would simply express the claret type as blazon A or blazon B, every bit the O claret blazon is recessive. To demonstrate blazon O blood, you must have both copies of the factor.
Question: What percentage of African Americans have blazon AB- claret?
Respond: 0.3% of African Americans have type AB- blood.
Question: What percentage of African Americans have blazon A- blood?
Respond: Co-ordinate to the American Reddish Cantankerous, just 2% of African Americans have blazon A- claret. This would be a rare claret type for this demographic.
Question: I'k from the Greatcoat Verde Islands off the w declension of Africa. I have AB+ claret. Is this normal?
Respond: According to The Distribution of ABO Claret Grouping System In Porto Novo Commune Of Cape Verde Islands, a enquiry paper by Peter Okeke in 2009, the following blood types were observed (from 750 samples):
320 people were Type O (43%)
226 people were Blazon A (30%)
167 people were Type B (22%)
37 people were Type AB (5%)
Having Blazon AB claret is rare, only non unheard of among the Greatcoat Verde population.

I have AB, my dad was O- and my mom is O- is it possible for bloodtype O to have a child with blood blazon AB
Carol Walker on August 15, 2019:
I have AB-, my Dad was O-. Is there any mode I tin find out where negative RH came from within the family? (
Leah Lefler (author) from Western New York on August 12, 2019:
It is important to realize the Rh type and claret type are not linked. Blazon O blood is the almost common type of blood in the USA with a positive Rhesus factor. The negative Rh does make O- blood rarer than O+ claret, but it is all the same not the rarest blood blazon. AB- is the rarest, followed by B-, then AB+, then A-. Approximately 6.half dozen% of the US population has type O- claret, Stan, so it is not extremely common, just also not rare. The highest prevalence of O- claret is establish in Spain and the Great britain (ix% of the population), though many countries in Europe have a prevalence betwixt vi-9% of the population. Argentina also has a very high relative prevalence of people with the O- claret type.
Stan on August 12, 2019:
Does blood type tells u.s. something about our beginnings. I read where O negative is rare except among the Basque population of Iberia and the Celtic tribes of Great britain. How likely is O negative blood type connected with Scottish or Basque ancestry?
Leah Lefler (author) from Western New York on May 08, 2019:
It is likely your father's genotype is heterozygous, which means he carries one allele for B and ane allele for O. You inherited the B from your begetter and an O from your mother - since B is dominant, y'all have the B blood blazon. Your sister would have inherited the O from your male parent and an O from your mother, making her blood type O.
Tina on May 06, 2019:
My begetter is b+ and mother is o+. But, why is it that i have my fathers blood blazon and my sister has our mothers claret blazon.
Leah Lefler (author) from Western New York on February 06, 2019:
The O blood type is recessive, Reina, so your mother and father both carried the O allele and you happened to go both copies. Your brother'south male parent likewise carries the recessive gene for the O blood type, and he carries the same blood type (despite having a dissimilar father). Your parents could accept blazon A, B, or O blood and nonetheless have a child with type O, since the trait is recessive. The negative Rh factor is likewise recessive.
Reina on February 02, 2019:
I am O negative and my ii brothers. One of my brothers has a unlike male parent but nosotros accept the aforementioned mother. How is information technology that we take same mother, dissimilar father yet accept szmd blood type( O negative)?
EmG on Apr 20, 2017:
I am o positive and considerd African American in America. I was always told about having Indian ancestors on both sides. My mother is O besides and my begetter is A. Shouldn't this be proof that many African Americans are classified incorrectly in ethnicity and racial classifications. Many of u.s. have hard time claiming our rights as aboriginal people. What tin can we do to change this and let people know who they are. The African American has been looking for their ancestral past for generations and this can definitely shed light on giving us our missing piece to our heritage puzzle. Thank you!
Leah Lefler (author) from Western New York on June 14, 2015:
B positive is definitely a rare blood type! The most common blood blazon in the world is type O claret. I actually know someone with blazon AB+ blood, Anya - I always tell him how rare that is!
Anya on June 11, 2015:
I am B pos
It is not a common type despite what people say
it is a really a rare Rh pos claret type only 8 to 9 percentage of people have this blazon
The rarest Rh pos type is AB pos which is two-3% of people
Leah Lefler (author) from Western New York on January 22, 2015:
Carmel, there are genetic testing kits bachelor online for tracing ancestry through the Y chromosome. Blazon "Y-DNA" testing kits into google and you will likely exist able to decide the general ancestry using just your son'southward sample. Otherwise, a standard paternity test (as well bachelor online) will work, but you will need a sample from your partner and from your son to determine if your partner is his biological father.

It is interesting, isn't it? Kariannr, I wonder if the percentages will alter over time, equally people are very mobile at present. My own family has a lot of A blood types, but my aunt is O negative - she got the recessive genes the whole way circular!

I thought that was actually interesting how you explained different races having unlike percentages of negative Rh factor and the different countries where the unlike blood types are more mutual. I know that probably sounds really impaired, but I'1000 a medical laboratory science student, and any new information is awesome to me.
