During which phase of meiosis are homologous chromosomes lined up along the middle of the cell?

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

Answer: (D)

Verified step by step guidance

1. Recall the stages of meiosis, which include Meiosis I and Meiosis II, each with their own phases: Prophase, Metaphase, Anaphase, and Telophase.
2. Understand that during Meiosis I, homologous chromosomes pair up and separate, while during Meiosis II, sister chromatids separate.
3. Identify that in Metaphase I, homologous chromosome pairs (tetrads) line up along the metaphase plate (middle of the cell).
4. Note that in Metaphase II, individual chromosomes (consisting of sister chromatids) line up along the middle, not homologous pairs.
5. Therefore, the phase where homologous chromosomes line up along the middle of the cell is Metaphase I.
