Explanation / Answer

Rh incompatibility occurs if an Rh-negative mother and is carrying a child with an Rh-positive father.that is, blood cells from Rh positive baby cross mothers bloodstream, which can happen during pregnancy, labour and delivery.It can be developed in the baby if mother did not receive Rho(D) Immune Globulin.Rh negative child will not develop incompatibility in mother.
