Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called as respective DNA, because in these sequences, a small stretch of DNA is repeated many times. These sequences normally do not code fr any proteins, but they form a large portion of human genome. These sequence show high degree of polymorphism and form the basis of DNA fingerprinting. As the polymorphisms are inheritable from parents to children, DNA fingerprinting is the basis of paternity testing in case of disputes.
