During which phase of meiosis does the separation of homologous chromosomes occur?

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

Answer: (D)

Verified step by step guidance

1. Recall the main stages of meiosis: Meiosis I and Meiosis II, each with Prophase, Metaphase, Anaphase, and Telophase phases.
2. Understand that homologous chromosomes are pairs of chromosomes, one from each parent, that pair up during meiosis.
3. Identify that the separation of homologous chromosomes occurs during Anaphase I, where each homolog is pulled to opposite poles of the cell.
4. Note that Anaphase II involves the separation of sister chromatids, not homologous chromosomes.
5. Conclude that the correct phase for the separation of homologous chromosomes is Anaphase I.
