Gametogensis refers to the process of

Options

A. Fusion of two gametes
B. Fusion of two gametangia
C. Formation of two types of gametes
D. Formation of male gametes only.

Answer

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

1. **Understanding Gametogenesis**: Gametogenesis is the biological process through which gametes (reproductive cells) are produced. This includes both male and female gametes.

2. **Identifying Gametes**: In humans and many other organisms, the male gametes are called sperm, while the female gametes are called ova (singular: ovum).

3. **Location of Gametogenesis**: Gametogenesis occurs in the reproductive organs known as gonads. In males, this process takes place in the testes, and in females, it occurs in the ovaries.

4. **Types of Gametogenesis**:
- **Spermatogenesis**: This is the process of forming sperm in males.
- **Oogenesis**: This is the process of forming ova in females.

5. **Analyzing the Options**:
- **Option A**: Fusion of two gametes - This describes fertilization, not gametogenesis.
- **Option B**: Fusion of two gametangia - This is not relevant to gametogenesis.
- **Option C**: Formation of two types of gametes - This correctly describes gametogenesis, as it involves the production of both sperm and ova.
- **Option D**: Formation of male gametes only - This is incorrect as gametogenesis includes both male and female gametes.

6. **Conclusion**: Based on the analysis, the correct answer is **Option C: formation of two types of gametes**.
