If the mother is Rh negative and the father is Rh positive and homozygous for the Rh factor,all the children will be Rh positive.Only Rh-positive children of an Rh-negative mother are at risk for Rh incompatibility.If the mother is Rh negative and the father is Rh positive and heterozygous for the factor,there is a 50% chance that each infant born of the union will be Rh positive and a 50% chance that each will be born Rh negative.
