Explain DNA polymorphism as the basis of genetic mapping of human genome.

Text Solution

Verified by Experts

Polymorphism is inherited from parents to children. So, it is useful for the identification (forensic application) and paternity testing. It arises due to mutations and also plays an important role in evolution and speciation. These mutations in the non-coding sequences have piled up with time and form the basis of DNA polymorphism. It is the basis of genetic mapping of human genome as well as DNA fingerprinting
