Mary has type a blood. her son bill has type ab blood. which blood type does bill's dad have if he is homogenous for blood type? a b ab o

Answer;

Blood group B

Explanation;Mary has blood type A, and the son has blood type AB.An individual with blood type A must have either one or two copies of A allele, that is either AA, or AO genotype. Similarly with blood group B, the genotype may be either be BB or BO. Therefore, since Mary has blood group A, and the son Bill has blood group AB, it means that the father would have blood group B. This is because Mary will pass A allele to their son and the father will pass B allele to the son.
