If both parents are Rh+ and have mixed genes (+ -), then it is possible that each of them will give the - gene to their child, making the child Rh- (- -). (there is a 25% chance that the child will be Rh- and 75% chance that the child will get a positive from either one or both parents)

If one parent is Rh+ and has 2 positive genes (+ +) then it doesn't matter what the other parent is, all the children will be Rh+ Hope this helps.

Sometimes we put up walls not to keep people out, but to see who cares enough to break them down.
