Answer 1

Answer: (D)

all of these.

Answer 2

High milk yielding varieties of cows are obtained by use of surrogate mothers, super ovulation, artificial insemination. To get an increased yield of milk surrogate mothers are used in dairy. Superovulation is the hormonal stimulation of multiple ovarian follicles resulting in release from the ovary of a larger number of oocytes (ova) than normal. So, implantation into surrogate mothers increases the number of offspring, usually from highly selected cows. Artificial insemination is a reasonably straight forward process to remove semen from a chosen male animal, and transfer it into a female, at the appropriate stage of the oestrous cycle. This process is well developed in case of dairy cattle breeding for more milk production.
