PATHOLOGY

Detailed explanation-1: -As you can see in the image to the right, these two parents can have an O child. In fact, every one of their children would have a 1 in 4 chance for being O.

Detailed explanation-2: -Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.

Detailed explanation-3: -Any answers? If a father’s blood group is o+ and mothers’s is AB+, what would their children be? The genotype of the father or possible genes he could pass on would be O O; the mother, A B. The genotype of the children would be AO & BO.

Detailed explanation-4: -Moreover, when IA and IB are present, both alleles are expressed, and the blood group type is AB. If a child’s blood group is ‘O’, both of the parents should have at least one i allele. Therefore, parents having ‘AB’ and ‘O’ blood group cannot have a child with blood group ‘O’.
