What about ABO blood type?

Answer 1

Here are the different blood types and corresponding genotypes that people can have:

* A (IAIA or IAi)

* B (IBIB or IBi)

* AB (IAIB)

* O (ii)

Collectively, these are known as ABO blood types, but you cannot be an ABO person! To be O, you must be homozygous recessive (genotype ii), so you cannot be A, B, or AB, because all of those require at least one dominant allele.

Answer 2

I'm not sure why you say "can't" because anyone - who meets all the other requirements for giving blood - can give blood regardless of blood type. If you're asking because you were turned away, it's probably because they didn't need any more AB blood. AB blood can only be donated to other individuals with AB blood. and if you are AB+ it can only be donated to others with AB+ blood. so there is not as pressing a need for it as other blood types such as O, the "universal donor."

Answer 3

The A and B blood types are co-dominant. It is the universal recipient which means AB can revieve blood from blood type A, B, or O. Blood type O is the universal donor which means it can give blood to A, B, or O. Yet, it creates anti-bodies against those so it cant recieve blood from them, (except O of course) only give. Therefore, They all are controlled by seprate protiens expaling why they make anti-bodies against one another.

Answer 4

Short answer: ABO is the name of the gene that produces A, B, AB, O blood types.

First, let me point out that there are 32 blood-group systems identified in the human. Each of these can affect the outcome of a cross-match for a blood transfusion. However, it would be too confusing to identify yourself as a 32 part blood type, so we limit it to the two most important antigens/genes which are the ABO gene and Rh factor.

The usually identified blood types are:

• phenotye: Type A pos = genotype: AA or AO with Rh factor (++) or (+-)
• phenotye: Type A neg= genotype: AA or AO with Rh factor (--)
• phenotye: Type B pos = genotype: BB or AO with Rh factor (++) or (+-)
• phenotye: Type B neg = genotype: BB or AO with Rh factor (--)
• phenotye: Type O pos = genotype: OO with Rh factor (++) or (+-)
• phenotye: Type O neg = genotype: OO with Rh factor (--)
• phenotye: Type AB pos = genotype: AB with Rh factor (++) or (+-)
• phenotye: Type AB neg = genotype: AB with Rh factor (--)

Therefore, there are 4 ABO blood types combined with 2 Rh factors, for a total of 8 blood types that can easily be identified with a blood mixing kit.

Answer 5

A, B, AB, and O are blood types. They describe which antigens are present: A, B, both, or neither.

Answer 6

yes Actually, ABO is not possible, unless you have three parents.

Answer 7

ABO is not a blood type, it is simply the name of the series of blood groups in which type A, type B, and type O are included.
