In meiosis, chromatids separate at

Options

A. Anaphase I
B. Anaphase II
C. Diakinesis
D. Diplotene

Answer

**Step-by-Step Text Solution:**

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

2. **Chromatids Definition**: Chromatids are the two identical halves of a replicated chromosome, connected at a region called the centromere. Each chromosome consists of two sister chromatids before cell division.

3. **Stages of Meiosis**: In meiosis, chromatids separate during two key phases: Anaphase I and Anaphase II. However, the separation of chromatids specifically occurs in Anaphase II.

4. **Anaphase II**: During Anaphase II, the centromeres that hold the sister chromatids together divide. This allows the sister chromatids to be pulled apart and move toward opposite poles of the cell.

5. **Role of Spindle Fibers**: The separation of chromatids is facilitated by spindle fibers, which are structures that help pull the chromatids apart during cell division.

6. **Conclusion**: Therefore, the correct answer to the question "In meiosis, chromatids separate at" is Anaphase II.
