umm yeah...
AB positive / A positive / B positive
baby blood group will be A or O
Your baby could be either blood group A positive or B positive. Since the mother is O positive, she can only pass on an O allele. The father, being AB positive, can pass on either an A or B allele. So, the baby can inherit either blood type A or B from the father, making the baby either blood type A positive or B positive.
B positive
The chances are 50/50 between A+ and B+. If the baby is type O, it's not yours, dude.
Yes
A-
Is mom rh positive or negative?
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
Yes! Yes indeed. Does the baby look like the mailman? No. O parents can't make AB babies.
Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.
B+
