Question
Assertion (A): In MOET, hormones with progesterone-like activity are given to the cow for inducing superovulation.
Reason (R): The embryos at 4-6 cell stage are recovered and transferred to surrogate mothers.

Solution
The correct option is D Both assertion and reason are false
Multiple Ovulation Embryo Transfer Technology (MOET) is a part of controlled breeding experiments. These experiments are carried out to improve the quality of animals.
MOET includes the following steps:
The cow is administered with hormones having FSH-like activity to stimulate follicular maturation and superovulation (production of about 6-8 eggs instead of one egg per cycle is called super ovulation).
The super ovulated 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 early embryos collected are then transferred to surrogate mothers in which the further development of embryo takes place.
In the given question, assertion is false as hormones with FSH-like activity are given to cows but not progesterone-like activity.
FSH (follicle stimulating hormone) is secreted by the anterior pituitary and it helps in the growth and development of ovarian follicles. These follicles have the ovum/egg.
Progesterone hormone is needed to support and maintain a potential pregnancy.
Reason is also false as early embryos at 8-32 cell stage are transferred to surrogate mothers.
Hence, both assertion and reason are false.
