A daytime talk show is doing a spot about a child, his 'forgetful' mother, and the kid's two potential fathers. The talk show had enough money to find out the blood types of all of the characters involved, but doesn't know where to go from there to determine who the father of the child is. They have asked for your help, and provide you with these blood types: Mother: Type A Potential Father 1: Type A Potential Father 2: Type O Child: Type O 1.
