Question

Assertion (A): Cattle breeds can be improved by superovulation and embryo transplantation at 8-32 cell stage into a surrogate mother.

Reason (R): Superovulation in high milk-yielding cows is induced by injecting with hormones.

विकल्प

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

Explanation:

The assertion describes MOET: superovulation is followed by transfer of fertilised embryos at the 8–32-cell stage to a surrogate mother. Hormone injections induce superovulation, so the reason is true, but it does not explain the embryo-transplantation part of the assertion.
