Which of the following phase include meiosis during spermatogenesis ?

Options

A. Phase of multiplication
B. Phase of maturation division
C. Phase of growth
D. Spermiation

Answer

To determine which phase includes meiosis during spermatogenesis, we can analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Spermatogenesis**:
- Spermatogenesis is the process of sperm cell development that occurs in the seminiferous tubules of the testes. It involves several phases: multiplication, growth, maturation, and spermiation.

2. **Analyzing the Phases**:
- **Phase of Multiplication**:
- This phase involves the rapid division of sperm mother cells (spermatogonia) through mitosis. Therefore, this phase does not involve meiosis.
- **Phase of Growth**:
- In this phase, the primary spermatocytes grow and prepare for the next stage. It does not involve meiosis but rather the enlargement of cells.
- **Phase of Maturation**:
- This is the critical phase where meiosis occurs. The primary spermatocytes undergo meiosis, resulting in the formation of secondary spermatocytes. This is a reductional division, which is the hallmark of meiosis.
- **Phase of Spermiation**:
- This phase involves the release of mature sperm from the seminiferous tubules and does not involve meiosis.

3. **Conclusion**:
- The phase that includes meiosis during spermatogenesis is the **Phase of Maturation**.

### Final Answer:
- The correct answer is the **Phase of Maturation**.
