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

The dad has AB blood.

Explanation:

Based on the wording of this question, we don't even have to understand how blood types work. The word homogenous means the same. Since it says the dad's blood is homogenous to that of his son and the son's blood type is AB, we know that the dad's blood type must also be AB.
