Terminalization process starts in :-

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Terminalization**: Terminalization refers to the process during meiosis where the synaptonemal complex, which holds homologous chromosomes together, begins to break down. This process is crucial for the separation of homologous chromosomes.

2. **Analyzing the Options**:
- **Option 1: Lipotene**: In this stage, chromosomes begin to condense, but the synaptonemal complex is still present. Therefore, terminalization does not start here.
- **Option 2: Zygotene**: This is the stage where synapsis occurs, and homologous chromosomes pair up with the help of the synaptonemal complex. Terminalization does not occur in this stage.
- **Option 3: Diplotene**: This is the correct stage where terminalization begins. In diplotene, the synaptonemal complex starts to dissolve, leading to the separation of homologous chromosomes.
- **Option 4: Diakinesis**: In this stage, chromosomes are fully condensed and the synaptonemal complex has already been dismantled. Thus, terminalization does not start here.

3. **Conclusion**: Based on the analysis of each option, the terminalization process starts in the **Diplotene** stage of meiosis.

**Final Answer**: The terminalization process starts in **Diplotene**.
