Answer 1

AB, Ba, Ab, and ba. Use a punnet square and it’s easy to find.

Answer 2

Answer: Possible genotypes: AB, AO, BO, or OO

Explanation: The mother is heterozygous for type A blood so her genotype must be AO. The father is heterozygous for type B blood so his genotype must be BO. After crossing the two in a punnet square, you’ll get the listed genotypes. The phenotypes for this same problem would be blood type AB, type A, type B or type O, because types A and B are dominant to type O.
