In sexual reproduction, the gamete-forming cell division is:
ABinary fission
BMitosis, which doubles the chromosome number
CMeiosis, which halves the chromosome number
DFragmentation
Answer & Solution
Correct answer: C. Meiosis, which halves the chromosome number
1. Gametes must carry half the somatic chromosome number so that fertilisation restores it.
2. Meiosis is the special two-step division that achieves this halving.
3. Mitosis would preserve diploidy and is used for body cell maintenance.
