Chromosomes of a bivalent remain far apart from each other to the extent possible in

Options

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

Answer

To solve the question "Chromosomes of a bivalent remain far apart from each other to the extent possible in," we need to analyze the stages of meiosis where bivalents (homologous chromosomes) are present and their behavior during these stages.

### Step-by-Step Solution:

1. **Understanding Bivalents**: Bivalents are formed during meiosis when homologous chromosomes pair up. Each bivalent consists of two homologous chromosomes.

2. **Identifying Stages of Meiosis**: The relevant stages of meiosis where bivalents are present include:
- Leptotene
- Zygotene
- Pachytene
- Diplotene
- Diakinesis

3. **Analyzing Each Stage**:
- **Leptotene**: This is the first stage of prophase I where chromosomes start to condense but are not yet paired. They are not far apart as they are just beginning to condense.
- **Zygotene**: Here, homologous chromosomes begin to pair up, forming bivalents. They are closer together during this stage.
- **Pachytene**: The bivalents are fully formed, and crossing over occurs. The chromosomes are still paired closely.
- **Diplotene**: In this stage, the synaptonemal complex disassembles, and the bivalents begin to separate slightly, but they are still connected at chiasmata (points of crossing over).
- **Diakinesis**: This is the final stage of prophase I where chromosomes are fully condensed and the bivalents are separated as much as possible, preparing for metaphase.

4. **Conclusion**: The stage where chromosomes of a bivalent remain far apart from each other to the extent possible is **Diakinesis**.

### Final Answer:
The correct answer is **Diakinesis**.
