Detailed explanation-1: -No, a child with type B blood would not be the result of two parents with type A blood regardless of the genotypes. With type A blood, there are two genotype possibilities which are AO and AA.
Detailed explanation-2: -Although blood group studies cannot be used to prove paternity, they can provide unequivocal evidence that a male is not the father of a particular child. Since the red cell antigens are inherited as dominant traits, a child cannot have a blood group antigen that is not present in one or both parents.
Detailed explanation-3: -One parent with A and another with B will give their child either A, B, AB or O groups. One parent with A and another with AB will give their child either A, B or AB groups. One parent with A and another with O will give their child either A or O blood group.
Detailed explanation-4: -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.
