Answer 2

Answer:

blood groups A and B are dominant so when a person marries a women with blood group O it means that the blood alleles of the women are OO and if their daughter have blood group O then she got the O from mother and O from father which confirms that the father must have the blood alleles AO. hope u got the point!!
