Consider statements about animal husbandry: 1. Artificial insemination is used in cattle breeding. 2. Multiple ovulation embryo transfer increases herd quality. 3. Crossbreeding reduces genetic diversity. Which are correct? MCQ with Answer and Explanation

Artificial insemination (AI) is a widely used reproductive technology in cattle breeding, allowing the use of superior bull semen to improve the genetic merit of the herd without keeping the bull. Multiple Ovulation Embryo Transfer (MOET) involves stimulating a superior female to produce multiple eggs, fertilizing them, and transferring the embryos to surrogate mothers, rapidly increasing the number of high-quality offspring. Crossbreeding involves mating animals of different breeds to combine desirable traits and increase heterozygosity, thereby increasing, not reducing, genetic diversity. Thus, statements 1 and 2 are correct.
