Question

Assertion (A): In Multiple Oocyte Embryo Transfer Technology (MOET), more than one egg is produced per oestrous cycle by the cow

Reason (R): Cows are given hormones with FSH-like activity to induce superovulation

• A. Both assertion and reason are true and the reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. The assertion is true but reason is false
• D. The assertion is false but reason is true

Answer 1

The correct option is D The assertion is false but reason is true

MOET stands for Multiple Ovulation Embryo Transfer Technology (MOET) and hence the assertion is false.

MOET is a part of controlled breeding experiments aimed for herd improvement.

Cow is a non-primate mammal and its reproductive cycle is called the oestrus cycle. Normally, one egg is released per cycle. However, in MOET, hormones with FSH-like activity are administered to cows to produce more than one egg per cycle. This hormone induces follicular maturation and instead of one egg, about 6-8 eggs are produced per cycle. This is called superovulation. Hence, reason is true.

The superovulated female is either mated with a superior bull or artificially inseminated (semen of superior male is injected into the reproductive tract of the cow).

The fertilised eggs at 8–32 celled stage (early embryos) are recovered non-surgically.

The embryos collected are then transferred to surrogate mothers in which the further development of embryo takes place.

Hence, the assertion is false but the reason is true.
