Answer 2

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.
