Assertion (A): DNA fingerprinting is applied in paternity testing in case of disputes.
Reason(R): It employs the principle of polymorphism in DNA sequences as polymorphisms are inheritable from parent to children.

Options

A. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)
B. Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
C. Assertion (A) is true but reason (R) is false.
D. Assertion (A) is false but reason (R) is true.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "DNA fingerprinting is applied in paternity testing in case of disputes."
- This is true as DNA fingerprinting is a widely accepted method for determining biological relationships, including paternity.

2. **Understanding the Reason (R)**:
- The reason states that "It employs the principle of polymorphism in DNA sequences as polymorphisms are inheritable from parent to children."
- This is also true because DNA fingerprinting relies on identifying variations (polymorphisms) in DNA sequences that are inherited from parents.

3. **Analyzing the Relationship Between Assertion and Reason**:
- While both the assertion and reason are true, we need to determine if the reason correctly explains the assertion.
- The reason explains the mechanism behind DNA fingerprinting (polymorphism) but does not directly explain why it is used specifically for paternity testing.

4. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not adequately explain the assertion, the correct answer is that both are correct, but the reason is not the correct explanation of the assertion.

### Final Answer:
The answer is option B: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
