In meiosis I, the centromere undergoes

Options

A. Division between anaphase and interphase
B. Division between prophase and metaphase
C. Division but the daughter chromosomes do not separate
D. No division

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 from one diploid cell. It consists of two main stages: Meiosis I and Meiosis II.

2. **Focus on Meiosis I**: In Meiosis I, the key event is the separation of homologous chromosomes. Unlike mitosis, where sister chromatids separate, in Meiosis I, the centromeres do not divide.

3. **Chromosome Movement**: During Meiosis I, specifically during anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell. However, the centromeres remain intact, meaning that the sister chromatids are still connected at this stage.

4. **Centromere Behavior**: The centromere does not undergo division during Meiosis I. This is a critical distinction from Meiosis II, where the centromeres do divide, allowing for the separation of sister chromatids.

5. **Conclusion**: Based on the behavior of the centromere during Meiosis I, the correct answer to the question is that there is "no division" of the centromere during this phase.

**Final Answer**: In meiosis I, the centromere undergoes no division.
