Answer: Meiosis I anaphase.
- A Mitosis anaphase
- B Meiosis I anaphase
- C Meiosis II anaphase
- D Prophase I
Correct answer: B. Meiosis I anaphase
Explanation: Homologous chromosomes separate during Anaphase I (Meiosis I). Sister chromatids separate during Anaphase II.
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.
