Detailed explanation-1: -So, the correct answer is “Mother is Rh-ve and father is Rh+ve."
Detailed explanation-2: -Erythroblastosis fetalis classically results from Rho(D) incompatibility, which may develop when a woman with Rh-negative blood is impregnated by a man with Rh-positive blood and conceives a fetus with Rh-positive blood, sometimes resulting in hemolysis.
Detailed explanation-3: -If the father’s blood type is Rh negative, no further testing is needed. However, if the father’s blood type is Rh positive or their blood type isn’t known, your blood may be tested again between 18 to 20 weeks of pregnancy, and again at 26 to 27 weeks. You’ll also receive treatment to prevent erythroblastosis fetalis.
Detailed explanation-4: -Two blood group systems, Rh and ABO, primarily are associated with erythroblastosis fetalis. The Rh system is responsible for the most severe form of the disease, which can occur when an Rh-negative woman (a woman whose blood cells lack the Rh factor) conceives an Rh-positive fetus.
Detailed explanation-5: -It is caused by the destruction of neonatal red blood cells by maternal immunoglobulin G (IgG) antibodies. The formation of maternal antibodies in response to a fetal antigen is called isoimmunization.
