  • Yes. If your mom has an O- gene, then there's a 50/50 chance she'll pass it to you. Basically.

  • both your mother and your father would have had to pass the o gene to you. so your father theoretically can be a b or o. ab would be impossible. however in order for you to come out rh positive your father would have to be possitive. then its a 50/50. for instance, my mother is a- and my father is a+ but im o+. now dh is ab- so my son can neither be o nor ab. in order to be ab youu have o get an a from one parent nd a b from another. and his rh is 50/50.
