The condition of erythroblastosis fetalis occurs only when
- A the husband is \(Rh ^{+}\)and wife is \(Rh ^{-}\)
- B the husband is \(Rh ^{-}\)and wife is \(Rh ^{+}\)
- C the mother is \(Rh ^{+}\)and wife is \(Rh ^{-}\)
- D the mother is \(Rh ^{-}\)and wife is \(Rh ^{+}\)
Answer & Solution
Correct Answer
(D) the mother is \(Rh ^{-}\)and wife is \(Rh ^{+}\)
Step-by-step Solution
Detailed explanation
(D) the mother is \(Rh ^{-}\)and wife is \(Rh ^{+}\),
Erythroblastosis fetalis occurs when an Rh-ve mother carries an Rh+ve fetus typically inherited from on Rh+ father. If fetal blood enters the mother's circulation, she may produce antibodies against the Rh factor. In subsequent pregnancies, these antibodies can cross the placenta and attack the red blood cells of an Rh+ve fetus, causing hemolytic disease.
