Polymorphism.

Answer

Polymorphism: The variation in DNA arising through mutation at non-coding sequences is known as Polymorphism. Such variations are unique to specific sites of DNA and can occur due to deletion, insertion or substitution of bases. It can be observed by making fragments of DNA sample and separating them through electrophoresis. The polymorphism in a DNA sequence is the basis of genetic mapping of the human genome as well as DNA fingerprinting.
