Detailed explanation-1: -One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Detailed explanation-2: -Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25% chance for a child to have OO, or blood type O.
Detailed explanation-3: -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’.
Detailed explanation-4: -So, the progeny formed if both parents are of O blood group is O. The Rh factor can be positive in heterozygous state and also in homozygous state. So, there can be possibility of being both Rh positive and Rh negative. The blood group can be both O positive or O negative.
