Meiosis occurs during

Options

A. Sporogenesis
B. Gametogenesis
C. Embryogenesis
D. 1 and 2

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of four haploid cells from one diploid cell. It consists of two sequential divisions: meiosis I and meiosis II.

2. **Identifying Processes Involving Meiosis**: Meiosis occurs during specific biological processes:
- **Sporogenesis**: This is the process of spore formation in plants. Spores are produced through meiosis and can develop into gametes or new organisms.
- **Gametogenesis**: This is the process of forming gametes (sperm and eggs) in animals and plants. Gametes are also produced through meiosis.

3. **Considering Other Options**: The question also mentions embryogenesis. However, embryogenesis is the process of development of the embryo from the zygote after fertilization and does not involve meiosis.

4. **Conclusion**: Since meiosis occurs during both sporogenesis and gametogenesis, the correct answer to the question is that meiosis occurs during these two processes.

5. **Final Answer**: Meiosis occurs during sporogenesis and gametogenesis.
