How many ova (eggs) are produced by one secondary oocyte?

Options

A. 1
B. 2
C. 4
D. none of these

Explanation

To answer the question of how many ova (eggs) are produced by one secondary oocyte, let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding Oocyte Development**:
- The female reproductive system produces oocytes through a process called oogenesis. The primary oocyte undergoes meiosis to form secondary oocytes.

2. **Meiosis Process**:
- During meiosis, a primary oocyte divides into two cells: one secondary oocyte and one polar body. The polar body is typically not functional and does not develop into an egg.

3. **Secondary Oocyte Division**:
- The secondary oocyte undergoes a second meiotic division, but this division is completed only if fertilization occurs. If fertilization happens, the secondary oocyte divides into one ovum (egg) and another polar body.

4. **Final Outcome**:
- Therefore, from one secondary oocyte, only one functional ovum (egg) is produced, along with a polar body that usually does not contribute to reproduction.

5. **Conclusion**:
- The answer to the question is that one secondary oocyte produces **one ovum (egg)**.

### Final Answer:
- **One ovum (egg)** is produced by one secondary oocyte.
