During meiosis, at which stage do homologous chromosomes separate and move toward opposite poles of the cell?

• A. Metaphase II
• B. Anaphase I
• C. Telophase I
• D. Prophase II

Answer: (B)

Verified step by step guidance

1. Recall the stages of meiosis, which consists of two divisions: Meiosis I and Meiosis II, each with its own phases (Prophase, Metaphase, Anaphase, Telophase).
2. Understand that during Meiosis I, homologous chromosomes (each consisting of two sister chromatids) pair up and then separate, while during Meiosis II, sister chromatids separate.
3. Identify that the separation of homologous chromosomes occurs specifically during Anaphase I, where the homologous pairs are pulled to opposite poles of the cell.
4. Note that Metaphase II and Prophase II occur in Meiosis II, which deals with the separation of sister chromatids, not homologous chromosomes.
5. Conclude that the correct stage for homologous chromosome separation is Anaphase I, as this is when homologous chromosomes move toward opposite poles.
