Detailed explanation-1: -Blood type A has antigen A, B has antigen B, AB has both antigens, while blood type O doesn’t carry any antigen. So, the child can have blood type A or B which differs from parents. Hence, the correct answer is option C.
Detailed explanation-2: -A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type. This is because type O blood is recessive and these individuals have two O alleles so the only allele they would be able to pass to a child would be “O".
Detailed explanation-3: -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).
