When one parent has type A blood and another has type B blood, their child can inherit one of four possible combinations of alleles: AA, AB, BB, or BO. If the child inherits an A allele from one parent and a B allele from the other, they will have AB blood type. If they inherit two A alleles, they will have type A blood. Similarly, if they inherit two B alleles, they will have type B blood. If they inherit one A allele and one O allele, they will have type A blood (because the A allele is dominant over the O allele). If they inherit one B allele and one O allele, they will have type B blood. Thus, all of the choices are possible blood types for the child.
