A human body cell has 46 chromosomes. After meiosis, gametes have:

Answer: 23.

A 92
B 46
C 23
D 12

Correct answer: C. 23

Explanation: Meiosis halves chromosome number. Human gametes (sperm/egg) have 23 chromosomes (haploid).

The cell cycle: G₁ (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G₂ (final checks before division), and M (mitosis itself) - together, G₁+S+G₂ make up interphase.

Concept context

Mitosis and meiosis: how cells divide for growth, repair, and reproduction.
