Detailed explanation-1: -In most cases, an O parent and an AB parent will have only A or B kids.
Detailed explanation-2: -If a man with type AB blood marries a woman with type O, the children will have blood types A and B. Each blood type will be a fraction of ½. This is because ‘A’ and ‘B’ alleles are dominant alleles on ‘O’.
Detailed explanation-3: -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-4: -There will be a 50% chance that their children would have type AB blood. There would be a 25% chance that their children would have type A blood with the genotype (AA).
