Question

Quizplus · Accepted Answer

A man with blood type O can only pass on an O allele to his offspring, as he has two O alleles. If the mother has blood type AB, she has both A and B alleles, and one of them will be passed on to the child. Therefore, it is not possible for a man with blood type O to father a child with blood type AB, as neither A nor B allele will be present in the father's genome to pass on to the child.
