Assertion :- Recessive mutation easily detectable in Neurospora
Reason :- Neurospora is diploid

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

To solve the question regarding the assertion and reason about Neurospora, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Recessive mutation is easily detectable in Neurospora."
- To evaluate this, we need to know whether recessive mutations can be easily identified in Neurospora.

2. **Understanding Neurospora**:
- Neurospora is a genus of fungi, specifically known as Neurospora crassa, which is primarily haploid in nature.
- This means that it has only one set of chromosomes (n), which allows for the expression of both dominant and recessive alleles.

3. **Evaluating the Reason**:
- The reason provided is "Neurospora is diploid."
- However, this statement is incorrect because Neurospora is predominantly haploid, not diploid.

4. **Connecting Assertion and Reason**:
- Since Neurospora is haploid, any recessive mutation present will be expressed as there is no dominant allele to mask its effect.
- Therefore, the assertion is true: recessive mutations are indeed easily detectable in Neurospora.
- The reason is false as Neurospora is not diploid.

5. **Conclusion**:
- The assertion is true, but the reason is false. Thus, the correct answer is that the assertion is true and the reason is false.

### Final Answer:
- **Assertion**: True
- **Reason**: False
