How everyone's blood is different (blood types).

Sagot :

Answer:

Tge differences in the antigens are what makes one person's blood different from someone else's.

Answer:

There are four blood types:  A, B, AB, and O.  We won't get into positive and negative Rh factors here.

A and B are codominant, meaning they act like partners when together, forming blood type AB.  A and B are both dominant to O.  O is completely recessive to all other blood types, meaning that the genotype must contain two O alleles to have Type O Blood.

Type A blood can be AA (h0m0zygous) or AO (heterozygous)

Type B blood can be BB (h0m0zygous) or BO (heterozygous)

Type AB blood is AB (heterozygous)

Type O blood is OO (h0m0zygous)

The various blood types can be combined using Punnett squares to predict probabilities of various blood types.

I hope this answers your question.
