The second meiotic division of ………..P …….. is unequal and results in the formation of ………. Q …….. .
Select the appropriate option for P and Q.

Options

A. P-secondary spermatocytes, Q-spermatids
B. P-primary oocyte, Q-ovum
C. P-secondary oocyte, Q-polar body
D. P-primary spermatocytes, Q-spermatids

Answer

To solve the question, we need to identify what "P" and "Q" represent in the context of the second meiotic division.

### Step-by-Step Solution:

1. **Understanding Meiosis**:
- Meiosis consists of two divisions: Meiosis I and Meiosis II. The first division is reductional, and the second division is equational. However, in certain cases, the second meiotic division can be unequal.

2. **Identifying P**:
- The question states that the second meiotic division is unequal. This is characteristic of oogenesis (the formation of ova in females), where the primary oocyte undergoes meiosis to form a secondary oocyte and a polar body.
- Therefore, "P" refers to the **secondary oocyte**, which is the product of the first meiotic division.

3. **Identifying Q**:
- The unequal division during the second meiotic division results in the formation of one ovum (mature egg) and one polar body.
- Thus, "Q" refers to the **polar body**, which is a small cell that is a byproduct of oocyte division and typically does not participate in fertilization.

4. **Final Answer**:
- Based on the above reasoning, we conclude that:
- P = Secondary oocyte
- Q = Polar body

### Conclusion:
The correct answer is:
- P = Secondary oocyte
- Q = Polar body
