A man's blood group is AB. What is the probability of the man giving birth to a child with blood group O?
Answer Details
A man with blood group AB has two different alleles (A and B) and no allele for O. For the man to pass on blood group O to his child, he must contribute an O allele. However, since he does not have an O allele, he cannot pass it on to his child. Therefore, the probability of the man giving birth to a child with blood group O is 0%.
