VNTR

VNTR's are used in DNA fingerprinting.
PCR has supplanted RFLP by Southern blotting and hybridization in analysis of VNTR's.
Simple sequence repeats can be used as genetic markers.
Details on many VNTR markers used by the US FBI are available.

Essentially, these VNTR's are small repeats of DNA sequence that exist in multiple copies, and the number of these repeats can vary.

DNA sequences that are present in many copies per chromosome set. Repetitive DNA sequences may be closely linked (eg satellite DNA or VNTR loci) or dispersed throughout the genome or parts of the genome (eg alu family).

VNTR Variable number tandem repeat. A type of DNA sequence found in eukaryotic genomes, in which a short sequence is repeated. The number of repeats varies between individuals and is used as a basis for genetic identification.
