Secondary spermatocyte undergo second meiotic division

Answer

### Step-by-Step Solution:

1. **Understanding Spermatogenesis**: Spermatogenesis is the process of sperm cell development that occurs in the seminiferous tubules of the testes.

2. **Role of Spermatogonia**: The process begins with spermatogonia, which are the sperm mother cells. Some of these spermatogonia differentiate into primary spermatocytes.

3. **First Meiotic Division**: Each primary spermatocyte undergoes the first meiotic division (meiosis I), resulting in two secondary spermatocytes. At this stage, the number of chromosomes is halved from 46 (diploid) to 23 (haploid) in each secondary spermatocyte.

4. **Second Meiotic Division**: Each secondary spermatocyte then undergoes the second meiotic division (meiosis II). This division is similar to mitosis, where the two secondary spermatocytes divide to produce a total of four haploid spermatids.

5. **Formation of Spermatids**: Thus, from one primary spermatocyte, after both meiotic divisions, four haploid spermatids are produced. These spermatids will eventually mature into sperm cells.

6. **Conclusion**: Therefore, the secondary spermatocyte undergoes the second meiotic division to produce haploid spermatids.
