Assertion : Polymorphism in DNA sequence is the basis of genetic mapping of human genome as well as of DNA fingerprinting . Reason : Polymorphism (variation at genetic level) not arises due to mutations.

A and R both are true and R is the correct explanation of the A . A and R both are false . A and R both are true but R is not the correct explanation of the A . A is true but R is false .

A is true but R is false .

The polymorphism in DNA sequence is the basis of genetic mapping of human genome as well as of DNA fingerprinting. Polymorphism (variation at genetic level) arises due to mutations. New mutations may arise in an individual either in somatic cells or in the germ cells .
