Options

A. 8
B. 6
C. 2
D. 4

Answer

To determine how many sperm are produced from one primary spermatocyte, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Starting Cell**: The process begins with a primary spermatocyte, which is a diploid cell (2n).

2. **Meiosis I**: The primary spermatocyte undergoes the first meiotic division (Meiosis I). This division reduces the chromosome number by half, resulting in two secondary spermatocytes. Each secondary spermatocyte is haploid (n).

3. **Meiosis II**: Each secondary spermatocyte then undergoes the second meiotic division (Meiosis II). This division also results in the formation of two cells from each secondary spermatocyte.

4. **Total Sperm Production**: Since there are two secondary spermatocytes produced from one primary spermatocyte, and each secondary spermatocyte produces two spermatids, the total number of spermatids (which will develop into sperm) produced from one primary spermatocyte is:
- 2 secondary spermatocytes × 2 spermatids per secondary spermatocyte = 4 spermatids.

5. **Conclusion**: Therefore, from one primary spermatocyte, a total of **four sperm** are produced.

### Final Answer:
The answer is **4**.
