Which of the following is a common technique used to separate sperm with X and Y chromosomes in animal breeding programmes?
- A. Sex sorting by flow cytometry
- B. Artificial insemination
- C. Embryo transfer
- D. In vitro fertilization
Answer: A. Sex sorting by flow cytometry
Flow cytometry can distinguish sperm based on DNA content, allowing sex sorting. It is used in selective breeding to obtain offspring of desired sex.

Which of the following pairs is correctly matched?
- A. Sericulture — rearing of bees
- B. Apiculture — rearing of silkworms
- C. Pisciculture — breeding and rearing of fish
- D. Animal husbandry — cultivation of crops
Answer: C. Pisciculture — breeding and rearing of fish
Pisciculture refers to the breeding and rearing of fish under controlled conditions. The other pairs are incorrectly matched.

Which of the following is the most appropriate sequence in silkworm rearing for silk production?
- A. Egg → pupa → larva → cocoon
- B. Egg → larva → cocoon → pupa
- C. Larva → egg → pupa → cocoon
- D. Pupa → larva → egg → cocoon
Answer: B. Egg → larva → cocoon → pupa
Silkworms hatch from eggs into larvae, and the larva spins a cocoon before pupation. The cocoon is the commercial source of silk.
