Poleward movement of homologous chromosomes takes place at

Options

A. Anaphase-I
B. Diakinesis
C. Metaphase-II
D. Anaphase-II

Answer

To solve the question regarding the poleward movement of homologous chromosomes, we need to analyze the options provided and identify the correct phase of cell division where this movement occurs.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the phase in which homologous chromosomes move towards opposite poles. This movement is crucial during cell division, specifically meiosis.

2. **Evaluate Option 1: Anaphase 1**:
- In Anaphase 1 of meiosis, homologous chromosomes are separated and pulled towards opposite poles of the cell. This is the key characteristic of Anaphase 1.
- **Conclusion**: This option is correct.

3. **Evaluate Option 2: Diakinesis**:
- Diakinesis is the final stage of prophase 1 in meiosis where chromosomes condense and become visible, and chiasmata terminalization occurs. There is no movement of chromosomes towards the poles in this stage.
- **Conclusion**: This option is incorrect.

4. **Evaluate Option 3: Metaphase 2**:
- In Metaphase 2, chromosomes are aligned at the equatorial plane of the cell, not moving towards the poles.
- **Conclusion**: This option is incorrect.

5. **Evaluate Option 4: Anaphase 2**:
- In Anaphase 2, sister chromatids are separated and move towards opposite poles. However, this phase deals with sister chromatids, not homologous chromosomes.
- **Conclusion**: This option is incorrect.

6. **Final Answer**: Based on the evaluation, the correct answer is **Option 1: Anaphase 1**.
