Which is wrong about oogenesis?

Options

A. Diploid oogonia
B. Growth phase
C. Formation of polar bodies
D. Equal meiotic division

Answer

To determine which statement about oogenesis is incorrect, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Oogenesis**:
- Oogenesis is the process of formation and release of the ovum (egg).
- It begins with a diploid cell known as oogonia (2n), which undergoes a series of divisions to ultimately produce a haploid ovum (n).

2. **Analyzing the Options**:
- **Option 1: Diploid Oogonia**:
- This statement is correct. Oogenesis starts with diploid oogonia, which are the precursor cells that undergo division.

- **Option 2: Growth Phase**:
- This statement is also correct. Oogenesis occurs during the growth phase of the female reproductive system, where the primary oocytes develop.

- **Option 3: Formation of Polar Bodies**:
- This statement is correct as well. During oogenesis, when a primary oocyte undergoes meiosis, it produces one secondary oocyte and one or more polar bodies. The polar bodies are smaller and contain less cytoplasm.

- **Option 4: Equal Meiotic Division**:
- This statement is incorrect. During oogenesis, the meiotic division is unequal. The primary oocyte divides to form one large secondary oocyte (which becomes the ovum) and one or more smaller polar bodies. The polar bodies are produced to discard the extra genetic material and are not functional gametes.

3. **Conclusion**:
- The incorrect statement about oogenesis is "equal meiotic division." The correct answer is that oogenesis involves unequal meiotic division.

### Final Answer:
The wrong statement about oogenesis is "equal meiotic division."
