Detailed explanation-1: -If the father’s blood group is O, he has the genotype IOIO or (ii) . The mother has blood type AB, which means that her genotype would be IAIB. The possible combinations of these two groups would result in children having genotypes IAIO or IBIO, which would give them blood groups A or B respectively.
Detailed explanation-2: -One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Detailed explanation-3: -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).
Detailed explanation-4: -F1 generation phenotypic ratio = 1 A group : 2 AB group : 1 B group; hence, parents with AB blood group can have a child with A, AB and B blood group. Correct option is “B".
