Options

A. 4
B. 1
C. 16
D. 32

Answer

To solve the question regarding the number of sperms formed from four spermatocytes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Spermatogenesis**:
- Spermatogenesis is the process by which spermatocytes develop into sperm cells. It involves several stages, starting from spermatogonia to primary spermatocytes, secondary spermatocytes, and finally to spermatids, which mature into sperm.

2. **Identify the Types of Spermatocytes**:
- There are two types of spermatocytes:
- **Primary Spermatocytes**: These are diploid cells (2n) that undergo meiosis.
- **Secondary Spermatocytes**: These are haploid cells (n) that result from the first meiotic division of primary spermatocytes.

3. **Meiosis Process**:
- Each primary spermatocyte undergoes meiosis I to produce two secondary spermatocytes.
- Each secondary spermatocyte then undergoes meiosis II to produce a total of four spermatids from one primary spermatocyte.

4. **Calculate the Total Sperm from Four Spermatocytes**:
- Since one primary spermatocyte produces four spermatids (which mature into sperm), for four primary spermatocytes:
- Total sperm = Number of primary spermatocytes × Sperm produced per primary spermatocyte
- Total sperm = 4 × 4 = 16

5. **Conclusion**:
- Therefore, the total number of sperms formed from four spermatocytes is **16**.

### Final Answer:
The number of sperms formed from four spermatocytes is **16**.
