AIIMS 2019 Botany DNA Fingerprinting Assertion Reason Question
Assertion: DNA fingerprinting is applied in paternity testing in case of disputes. Reason: It employs the principle of polymorphism in DNA sequences as the polymorphisms are inheritable from parent to children.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option A is correct because both the assertion and reason are true: DNA fingerprinting is indeed used in paternity testing to resolve disputes, and it relies on the principle of polymorphism in DNA sequences, which are inherited from parents to offspring. This inheritance allows for the comparison of genetic markers between parents and children to establish biological relationships.
Option B is incorrect because while both statements are true, the reason directly explains the assertion. Option C is incorrect as it claims the reason is false, which is not the case. Option D is incorrect because it asserts that both statements are false, contradicting the established use of DNA fingerprinting in paternity testing.
