Blood Types Problem Set

Problem 4: What are the potential blood types of the father of my son?

I have been reading your info about inheritance of blood types and I am getting very confused! I am trying to figure out what blood type the father of my son could have since my son and I are both type A+. Also, my brother is type 0 and my mom is A+. We can't find anything that explains how this can be. Could you please help??? --From a concerned Mom

The father could be:

A. A, AB, B, or O

B. Either A or B

C. Either A or O
