Process of sexual reproduction which involves meiosis and syngamy is

Options

A. Apomixis
B. Amphimixis
C. Agamospermy
D. Diplospory.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the process of sexual reproduction that involves both meiosis and syngamy.

2. **Defining Key Terms**:
- **Meiosis**: This is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid gametes (sperm and egg cells).
- **Syngamy**: This refers to the fusion of male and female gametes during fertilization, leading to the formation of a zygote.

3. **Analyzing the Options**:
- **A. Apomixis**: This is a form of asexual reproduction where seeds are produced without fertilization, thus not involving meiosis or syngamy.
- **B. Amphimixis**: This is the process of sexual reproduction that involves the fusion of male and female gametes (syngamy) and requires meiosis to produce these gametes.
- **C. Agamospory**: Similar to apomixis, this involves the production of seeds from an unfertilized ovule, thus not involving meiosis or syngamy.
- **D. Diplospory**: This refers to a specific type of spore formation that does not involve the typical sexual reproduction processes.

4. **Identifying the Correct Answer**: Based on the definitions and analysis, the only option that involves both meiosis (to produce gametes) and syngamy (the fusion of these gametes) is **B. Amphimixis**.

5. **Conclusion**: Therefore, the process of sexual reproduction which involves meiosis and syngamy is **Amphimixis**.
