Erythroblastosis fetalis, also known as hemolytic disease of the newborn, occurs when there is incompatibility between maternal and fetal blood types. In the case of erythroblastosis fetalis, specifically, the incompatible factor is the Rh factor. When the mother is Rh-negative and the fetus is Rh-positive, the mother's immune system may produce antibodies against the Rh factor, which can cross the placenta and attack the fetal red blood cells, causing anemia, jaundice, and potentially other complications.
