Quizplus · Accepted Answer

Rh incompatibility occurs when the mother is Rh-negative and the fetus is Rh-positive. This happens because the mother's immune system may recognize the Rh antigen on the fetus' red blood cells as foreign and produce antibodies against them. This can lead to hemolytic disease of the newborn, which can be severe and even fatal. If the mother is Rh-positive or the fetus is Rh-negative, there is no Rh incompatibility. Similarly, if both the mother and the fetus are Rh-positive, there is no Rh incompatibility.
