Reason: Gametes are formed by meiosis in female and by mitosis in male. a) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion. b) If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion. c) If Assertion is true but the Reason is false. d) If both Assertion and Reason are false.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question, we need to analyze the assertion and reason provided:

**Assertion:** In honeybee, female is diploid and male is haploid.
**Reason:** Gametes are formed by meiosis in female and by mitosis in male.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- In honeybees, the females are diploid (2n), meaning they have two sets of chromosomes. Specifically, female honeybees have 32 chromosomes (16 pairs).
- Males, on the other hand, are haploid (n), meaning they have only one set of chromosomes. Male honeybees have 16 chromosomes.

2. **Understanding the Reason:**
- The reason states that gametes are formed by meiosis in females and by mitosis in males.
- In females, meiosis occurs to produce haploid gametes (sperms or eggs) from diploid cells. This is correct.
- In males, the process is a bit different. Male honeybees develop from unfertilized eggs and are produced through a process called parthenogenesis, which involves mitosis rather than meiosis.

3. **Evaluating the Truth of the Assertion and Reason:**
- Both the assertion and the reason are true.
- However, the reason does not correctly explain the assertion because while it is true that females undergo meiosis to produce gametes, the statement about males is misleading. Males do not form gametes through mitosis in the same way as females; they are produced from unfertilized eggs.

4. **Conclusion:**
- Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct answer is option **b**: If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
