Synaptonemal complex between homologous chromosomes is dissolved in which stage of meiosis ?

Options

A. Diplotene
B. Diakinesis
C. Pachytene
D. Leptotene

Answer

To answer the question regarding the stage of meiosis in which the synaptonemal complex between homologous chromosomes is dissolved, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half and leads to the formation of gametes. It consists of two main stages: Meiosis I and Meiosis II, each having several phases.

2. **Identifying the Stages of Meiosis**: The stages of Meiosis I include:
- Prophase I (which is further divided into Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis)
- Metaphase I
- Anaphase I
- Telophase I

3. **Focus on Prophase I**: The synaptonemal complex forms during the early stages of Prophase I, particularly during Zygotene and Pachytene, where homologous chromosomes pair up and exchange genetic material.

4. **Dissolution of Synaptonemal Complex**: The synaptonemal complex is a protein structure that facilitates the pairing of homologous chromosomes. The dissolution of this complex begins during the Diplotene stage of Prophase I.

5. **Conclusion**: Therefore, the correct answer to the question is that the synaptonemal complex between homologous chromosomes is dissolved during the **Diplotene stage** of meiosis.

### Final Answer:
The synaptonemal complex between homologous chromosomes is dissolved in the **Diplotene stage** of meiosis.
