Arrange the following events in Multiple Ovulation Embryo Transfer Technology (MOET) chronologically.
(A) Non surgical recovery of fertilized eggs at 8-32 cells stage and transfer to surrogate mother.
(B) Administration of FSH hormone to cow.
(C) Mating with elite bull or artificially inseminated.
(D) Initiation of superovulation
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (B), (D), (C), (A)
In MOET, the cow is given FSH (B), which starts superovulation (D); it is then mated with an elite bull or artificially inseminated (C); the fertilised eggs at the 8–32 cell stage are recovered non-surgically and transferred to surrogate mothers (A).

NCERT Extract (Pre-rationalised edition, Chapter 9, Strategies for Enhancement in Food Production):
Animal Breeding – “… Multiple Ovulation Embryo Transfer Technology (MOET) is one such programme for herd improvement. In this method, a cow is administered hormones, with FSH-like activity, to induce follicular maturation and 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 recovered non-surgically and transferred to surrogate mothers.”
