Either: Not enough information, since the rh-factor can either be transmitted or not, so could be either. Equally challenging to see if you are a, b, or ab blood type, depending on mom's blood type. Can donate blood and they'll send you a donor card with your blood type & rh factor (and you will save 3 people's lives!).
