In meiosis, the centromere divides during

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells. It consists of two main stages: Meiosis I and Meiosis II.

2. **Phases of Meiosis**:
- Meiosis I includes Prophase I, Metaphase I, Anaphase I, and Telophase I.
- Meiosis II includes Prophase II, Metaphase II, Anaphase II, and Telophase II.

3. **Centromere Division**: The centromere is the region of the chromosome where the two sister chromatids are joined together. The division of the centromere is crucial for the separation of sister chromatids.

4. **Events in Meiosis I**: During Meiosis I, homologous chromosomes are separated. This occurs in Anaphase I, but the centromeres do not divide at this stage. Instead, the homologous chromosomes are pulled apart.

5. **Events in Meiosis II**: In Meiosis II, which is similar to mitosis, the centromeres do divide. This occurs during Anaphase II, where the sister chromatids are separated and pulled to opposite poles of the cell.

6. **Conclusion**: Therefore, the centromere divides during Anaphase II of Meiosis II.

**Final Answer**: The centromere divides during Anaphase II of meiosis.
