If one parent has a positive blood type, and the other has b positive,what are the probabl blood types of kids

Question

So, what is the likelihood of children having a certain blood type?

Answer 1

A, B, O AB

If both parents are homogeneous for A and B, the kids are 100% AB. If both parents are heterogeneous for A and B, then the kids have equal chance for A, B, O and AB.

Answer 2

It depends whether the parents are homozygous or heterozygous for each trait (blood type and Rh). It also defers if one parent is homozygous for one or both traits and the other is homozygous for one or both.

One parent's genotype can be: AA++, AA+-, AO++ or AO+-

And the other one's genotype can be: BB++, BB+-, BO++ or BO+-

The kids can have b;ood type of A+, A- , B+, B-, AB+, AB-. O+ or O-
