A mid body is formed during

Options

A. Animal cytokinesis
B. Plant cytokinesis
C. Metaphase
D. Both A and B

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks during which process a mid-body is formed. The options provided are animal cytokinesis, plant cytokinesis, metaphase, or both A and B.

2. **Identifying the Process**: A mid-body is a structure that forms during cytokinesis, which is the division of the cytoplasm following mitosis.

3. **Differentiating Cytokinesis in Animals and Plants**:
- In **animal cells**, cytokinesis involves the formation of a contractile ring that leads to the creation of a cleavage furrow, resulting in two separate cells. During this process, a mid-body is formed as a residual structure after the separation of sister chromatids.
- In **plant cells**, cytokinesis occurs differently. A cell plate forms between the dividing cells, and there is no formation of a mid-body.

4. **Analyzing the Options**:
- **Animal Cytokinesis**: Yes, a mid-body is formed.
- **Plant Cytokinesis**: No, a mid-body is not formed.
- **Metaphase**: No, this is a stage of mitosis, not cytokinesis.
- **Both A and B**: Incorrect, as only animal cytokinesis forms a mid-body.

5. **Conclusion**: Based on the analysis, the mid-body is specifically formed during animal cytokinesis.

6. **Final Answer**: The mid-body is formed during **animal cytokinesis**.
