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

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis is the process of sperm cell development that occurs in the male reproductive system. It involves several stages, starting from the primary spermatocyte to the formation of mature sperm.

2. **Primary Spermatocyte Formation**: The process begins with the formation of primary spermatocytes, which are diploid cells (2N). This means they contain two sets of chromosomes.

3. **First Meiotic Division**: Each primary spermatocyte undergoes the first meiotic division (meiosis I), resulting in the formation of two secondary spermatocytes. After this division, the number of chromosomes is halved, and the secondary spermatocytes are haploid (N).

4. **Second Meiotic Division**: Each secondary spermatocyte then undergoes the second meiotic division (meiosis II). This division is similar to mitosis, where each secondary spermatocyte divides to produce two spermatids.

5. **Final Outcome**: Therefore, from each secondary spermatocyte, two spermatids are produced. Since each spermatid is haploid (N), the final outcome from one secondary spermatocyte is two haploid sperm cells.

6. **Conclusion**: Thus, each secondary spermatocyte after the second meiotic division produces two haploid sperm cells.

**Final Answer**: Each secondary spermatocyte after the second meiotic division produces 2 haploid sperm cells.
