A member asked:
My mother is a+rh positive and so is my dad, my blood type is a-rh negative. how is this possible?
A doctor has provided 1 answer
Recessive genes: If each of your parents has one rh + and one rh- gene, they will both produce the rh antigen. But each of their offspring has a one out of four chance of inheriting the negative gene from both parents, which makes them (you) rh neg.
