A member asked:

Could you tell me if my mom is o positive what are her parents possible blood types?

A doctor has provided 1 answer

Blood typing: The 4 major blood groups are a, b, ab and o. If your mother is group o, than neither of her parents could be type ab. The others would be possible. Likewise, being rh positive means that at least one of your mother's parents were rh positive, but not necessarily both.

Dr Friedlander and 2 doctors agreed
