How many sperms are formed from 4 primary spermatocytes?

Options

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

Explanation

To determine how many sperm cells are formed from 4 primary spermatocytes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Spermatocytes**:
- Primary spermatocytes are derived from spermatogonia and are the cells that undergo meiosis to produce sperm.

2. **Meiosis Process**:
- Each primary spermatocyte undergoes meiosis, which consists of two divisions: meiosis I and meiosis II.
- During meiosis I, one primary spermatocyte divides into two secondary spermatocytes.
- During meiosis II, each secondary spermatocyte divides into two spermatids.

3. **Spermatid to Spermatozoa Conversion**:
- Each spermatid matures into a spermatozoon (sperm cell).
- Therefore, from one primary spermatocyte, a total of four spermatozoa are produced (2 secondary spermatocytes x 2 spermatozoa each).

4. **Calculating for 4 Primary Spermatocytes**:
- If one primary spermatocyte produces 4 spermatozoa, then 4 primary spermatocytes will produce:
\[ 4 \text{ primary spermatocytes} \times 4 \text{ spermatozoa per primary spermatocyte} = 16 \text{ spermatozoa} \]

5. **Final Answer**:
- Thus, the total number of sperm cells formed from 4 primary spermatocytes is 16.
