During oogenesis, each diploid oocyte produces.

Options

A. Four functional ova
B. wo functional eggs and two polar bodies
C. Four functional polar bodies
D. One functional egg and three polar bodies

Answer

**Step-by-Step Solution:**

1. **Understanding Oogenesis**: Oogenesis is the process of egg (ovum) formation in females. It begins with the diploid germ cells called oogonia.

2. **Formation of Primary Oocytes**: The oogonia undergo mitotic division to produce a large number of primary oocytes. Each primary oocyte is diploid (2n).

3. **Meiotic Division**: Each primary oocyte undergoes two meiotic divisions:
- **First Meiotic Division**: The primary oocyte divides into two unequal haploid cells: a larger secondary oocyte and a smaller first polar body.
- **Second Meiotic Division**: The secondary oocyte divides again, producing one large ovum and a smaller second polar body. The first polar body may also divide to form two additional polar bodies.

4. **Final Outcome**: The end result of oogenesis is one functional ovum (egg) and three polar bodies. The polar bodies are typically non-functional and degenerate.

5. **Conclusion**: Therefore, during oogenesis, each diploid oocyte produces one functional egg and three polar bodies.

**Final Answer**: One functional egg and three polar bodies.
