Options

A. Spermatogonia–Spermatid–Spermatocyte –Sperms
B. Spermatocyte–Spermatogonia–Spermatid –Sperms
C. Spermatogonia–Spermatocyte–Spermatid –Sperms
D. Spermatid–Spermatocyte–Spermatogonia –Sperms

Answer

To determine the correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis, we need to understand the process of spermatogenesis. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Spermatogonia**: The process begins with spermatogonia, which are the diploid germ cells located in the seminiferous tubules of the testes. These cells undergo mitosis to produce more spermatogonia or differentiate into primary spermatocytes.

2. **Primary Spermatocyte**: The spermatogonia that undergo differentiation become primary spermatocytes. These cells are also diploid and undergo meiosis I.

3. **Secondary Spermatocyte**: After meiosis I, each primary spermatocyte divides to form two secondary spermatocytes. These cells are haploid.

4. **Spermatid**: The secondary spermatocytes then undergo meiosis II, resulting in the formation of spermatids. These are also haploid cells.

5. **Spermatozoa (Sperms)**: Finally, the spermatids undergo a process called spermiogenesis, where they differentiate into mature sperm cells (spermatozoa). During this process, they develop a flagellum and lose excess cytoplasm.

### Correct Sequence:
The correct sequence of spermatogenetic stages leading to the formation of sperms is:
- **Spermatogonia → Primary Spermatocyte → Secondary Spermatocyte → Spermatid → Spermatozoa (Sperms)**

### Conclusion:
Thus, the correct answer to the question is option number three: **Spermatogonia, Spermatocyte, Spermatid, Spermatozoa**.
