Assertion :- Most of the X-linked disorders can not be eliminated easily from nature and our gene pool.
Reason : X-linked dosorders are due to recessive genes.

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 analyze the given assertion and reason, we will break down the concepts step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Most of the X-linked disorders cannot be eliminated easily from nature and our gene pool."
- X-linked disorders are genetic conditions that are associated with genes located on the X chromosome. These disorders include conditions like hemophilia and color blindness.

2. **Understanding the Reason**:
- The reason provided is that "X-linked disorders are due to recessive genes."
- In genetics, recessive genes require two copies (one from each parent) to express the trait in females (XX), whereas males (XY) have only one X chromosome. Therefore, if a male inherits a recessive allele for an X-linked disorder, he will express that disorder because he does not have a second X chromosome to mask the effect.

3. **Analyzing the Assertion**:
- The assertion is true because X-linked disorders are often more prevalent in males due to their single X chromosome. Since these disorders are recessive, they can persist in the population, especially since females can be carriers (having one normal and one affected allele) without expressing the disorder.

4. **Analyzing the Reason**:
- The reason is also true because it correctly identifies that X-linked disorders are typically caused by recessive alleles. This characteristic contributes to the difficulty in eliminating these disorders from the gene pool.

5. **Conclusion**:
- Both the assertion and the reason are true, and the reason provides a correct explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: True
- **Conclusion**: The reason is a correct explanation of the assertion.
