If your genetic type is ++ or +-, your blood type will be Rh positive. Only if your genetic type is ? will you be Rh negative. This means that if both parents have Rh+ blood with the +- genes, they could have children who are ++, +-, or ?. In other words, their children could be either Rh positive or Rh negative. Children who are Rh negative can have parents who are either Rh positive or Rh negative.In the very simplest terms, you inherit a positive or a negative Rh type from each parent. So, you could wind up with two positives, two negatives or a positive-negative mix. The positive gene dominates, so a positive-negative combination will result in a positive type as well as having two positives. Only two negatives will produce a child with a negative type.
