Question

If parents are A and B, what are the possible genotypes of the parents? What are all the possible blood types of children? What if the parents are AB and A?

Answer 1

With analyses of this type, we say that one gene comes from Dad and one from Mom, resulting in 2 genes within a child. Some genes are dominant (meaning that if they are present, they determine that particular factor) and others are recessive (so the 2 genes in a person must be the same for that quality to win out).

Quick example - Brown eyes are dominant and blue eyes are recessive. There are 3 different ways the two genes can be: BB, Bb, bb. The first 2 have the dominant Brown gene and so that person will have Brown eyes. The last one has both genes as b and so that person will have blue eyes.

Answer 2

the children will be ab positive
