Given are the Rh blood groups of a couple.I.Father → Rh positive.II.Mother → Rh negative.The mother conceives an Rh positive child. In the given scenario, the chances of mother-foetus Rh incompatibility will be:
Correct answer: D. 100%
- A. 0%
- B. 25%
- C. 50%
- D. 100%
Explanation
In the given scenario, the mother is Rh-negative, and the child is Rh-positive. This situation can lead to Rh incompatibility, where the mother's immune system may produce antibodies against the Rh-positive blood cells of the foetus, potentially causing haemolytic disease of the newborn. Therefore, the chances of mother-foetus Rh incompatibility are 100%. Option A (0%) is incorrect because there is a definite risk of incompatibility. Option B (25%) and Option C (50%) are also incorrect because these percentages do not accurately represent the biological risk involved.
