Vedclass · Answer

(A) Erythroblastosis fetalis is a hemolytic disease of the newborn that occurs when there is an $Rh$ incompatibility between the mother and the fetus.This condition typically arises when an $Rh^-$ mother carries an $Rh^+$ fetus.During the first pregnancy,the mother's blood is exposed to the $Rh$ antigens of the fetus during delivery,leading to the formation of anti-$Rh$ antibodies in her blood.In subsequent pregnancies,if the fetus is again $Rh^+$,these maternal anti-$Rh$ antibodies cross the placenta and destroy the fetal red blood cells.Therefore,this condition occurs when the father is $Rh^+$ and the mother is $Rh^-$.
