One of the most frequently used techniques in DNA fingerprinting is

One of the most frequently used techniques in DNA fingerprinting is VNTR (Variable Number of Tandem Repeats). VNTR shows very high degree of polymorphism. It is a type of satellite DNA that is used as a probe in DNA fingerprinting.

Single-stranded conformation polymorphism (SSCP) analysis is a widely used screening method that allows identification of different genomic variants in a large sample of DNA.   

A SCAR is a genomic DNA fragment at a single genetically defined locus that is identified by PCR amplification using a pair of specific oligonucleotide primers.   

Amplified fragment length polymorphism (AFLP) is a PCR-based technique that uses selective amplification of a subset of digested DNA fragments to generate and compare unique fingerprints for genomes of interest.
