Question

A dna polymorphism is the basis of dna fingerprinting technique explain

Answer 1

DNA fingerprinting is a technique of printing the DNA finger is used for comparing the nucleotide sequences of fragments of DNA from different sources.
Polymorphism is the basis of genetic mapping of human genome as well as of DNA fingerprinting in DNA sequence.

Answer 2

Polymorphism are the variation at genetic level which arise due to mutations.

Depending on base composition length of segment, and number of repetitive units, the Satellite DNA is classified into many categories, such as microsatellites, minisatellites, etc. These sequences Show high degree of polymorphism and form the basis of DNA fingerprinting.

Since DNA from every tissue, from an individual show the same degree of polymorphism, they become very useful identification tool in forensic applications.

If an inheritable mutation is observed in a population at high frequency, it is referred to as DNA polymorphism. These mutations keep on accumulating generation after generation, and form one of the basis of variability or polymorphism.

For evolution and speciation, search polymorphism play very important role.
