The incompatibility occurs when a Rh-negative mother gives birth to a Rh-positive fetus. During the birth process, the mother may be exposed to the Rh-positive fetal blood and develop anti-Rh antibodies, which can then cross the placenta and attack the Rh-positive fetal red blood cells, leading to hemolytic disease of the newborn.
