Each secondary spermatocyte after second meiotic division produces

Options

A. Four haploid spermatids
B. Only one haploid spermatid
C. Two haploid spermatids
D. Two diploid spermatids.

Answer

To solve the question, "Each secondary spermatocyte after the second meiotic division produces," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Spermatogenesis**:
- Spermatogenesis is the process of sperm formation that occurs in the male reproductive system. It involves several stages, including the transformation of spermatogonia into spermatozoa.

2. **Identify the Starting Point**:
- The process begins with spermatogonia, which are diploid (2n) cells. These undergo mitotic division to produce primary spermatocytes.

3. **Primary Spermatocytes**:
- Each primary spermatocyte is diploid (2n) and undergoes the first meiotic division (meiosis I) to produce two secondary spermatocytes.

4. **Secondary Spermatocytes**:
- Each secondary spermatocyte is haploid (n) and undergoes the second meiotic division (meiosis II).

5. **Meiosis II**:
- During meiosis II, each secondary spermatocyte divides to produce two spermatids. Since each secondary spermatocyte divides, the result is two haploid spermatids per secondary spermatocyte.

6. **Conclusion**:
- Therefore, each secondary spermatocyte after the second meiotic division produces **two haploid spermatids**.

### Final Answer:
- The correct answer is **C: two haploid spermatids**.
