Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Cattle breeds can be improved by super ovulation and embryo transfer technique. It is also known as Multiple Ovulation Embryo Transfer Technology (MOET). In this method, a cow is administered hormones with FSH like activity, to induce super ovulation instead of one egg, which they normally yield per cycle they produce 6-8 eggs. The animal is either mated with an elite bull or artificially inseminated. The fertilised eggs at 8-32 cells stages are removed non surgically and transferred to surrogate mothers. The genetic mother is available for another round of super ovulation.Therefore, the correct answer is option B.
