Poleward movement of dyads occurs during

Options

A. metaphase I
B. metaphase II
C. anaphase I
D. anaphase II

Answer

To solve the question regarding the poleward movement of dyads, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dyads**:
- A dyad refers to a double chromosome formed during meiosis. It consists of two sister chromatids joined together.

2. **Identifying the Phases of Meiosis**:
- Meiosis consists of two main stages: Meiosis I and Meiosis II. Each of these stages has several phases: Prophase, Metaphase, Anaphase, and Telophase.

3. **Analyzing the Options**:
- **Option A: Metaphase 1** - In this phase, chromosomes align at the metaphase plate, but they do not move toward the poles.
- **Option B: Metaphase 2** - Similar to Metaphase 1, chromosomes align at the metaphase plate in the second meiotic division.
- **Option C: Anaphase 1** - This is the phase where homologous chromosomes (dyads) are pulled apart and move toward opposite poles of the cell.
- **Option D: Anaphase 2** - In this phase, sister chromatids are separated and move toward the poles, but it is not the initial formation of dyads.

4. **Conclusion**:
- The poleward movement of dyads occurs during Anaphase 1 of meiosis. Therefore, the correct answer is **Option C: Anaphase 1**.

### Final Answer:
The poleward movement of dyads occurs during **Anaphase 1**.
