Answer: 4.
- A 8
- B 6
- C 16
- D 4
Correct answer: D. 4
Explanation: Meiosis halves the chromosome number, so a 2n = 8 cell forms haploid gametes with n = 4 chromosomes.
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.
