Spermatogonia develop through :

Options

A. Amitosis
B. Mitosis
C. Meiosis I
D. Meiosis II

Answer

To solve the question "Spermatogonia develop through:", we will analyze the options provided and understand the process of spermatogenesis.

### Step-by-Step Solution:

1. **Understanding Spermatogonia**:
- Spermatogonia are the male germ cells located in the seminiferous tubules of the testes. They are the precursor cells that eventually develop into sperm.

2. **Identifying the Process of Development**:
- Spermatogonia undergo a series of divisions to develop into mature sperm. The initial stage involves the multiplication of these cells.

3. **Mitosis**:
- Spermatogonia primarily develop through **mitosis**. This is a type of cell division that results in two identical daughter cells, maintaining the diploid chromosome number.
- In the male reproductive system, spermatogonia undergo mitotic divisions to increase their numbers.

4. **Meiosis**:
- After several rounds of mitosis, spermatogonia differentiate into primary spermatocytes, which then undergo **meiosis**.
- Meiosis consists of two stages: Meiosis I and Meiosis II.
- Meiosis I reduces the chromosome number by half, producing secondary spermatocytes, and Meiosis II further divides these into spermatids.

5. **Conclusion**:
- Since the question specifically asks about the development of spermatogonia, the correct answer is that spermatogonia develop through **mitosis**.

### Final Answer:
The correct answer is **mitosis** (Option 2).
