Question

Which disease occurs due to Rh incompatibility?

• A. Sickle cell anaemia
• B. Thalassemia
• C. Erythroblastosis foetalis
• D. Haemophilia

Answer 1

The correct option is C Erythroblastosis foetalis

. If an Rh-positive man marries an Rh-negative woman, then the first foetus (and foetuses thereafter) will be Rh-positive. In this case, the Rh-positive antigen from the foetus will enter into the bloodstream of the mother and there will be the formation of anti-Rh antibodies in mother’s body. During her second pregnancy, these antibodies will attach the red blood cells of the Rh-positive foetus and coagulate the blood, resulting in severe complications. These complications arising due to Rh incompatibility are called erythroblastosis foetalis.

So, the correct answer is 'Erythroblastosis foetalis'.
