Explanation:
Detailed explanation-1: -If a man is homozygous for the blood group O i.e., genotype will be OO and he marries a female with blood group AB. Then the offspring will have blood group A, B according to the punnet square.
Detailed explanation-2: -A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
