VNTR (variable number of tandem repeats) A DNA polymorphism caused by the presence of a variable number of short tandem repeated DNA sequences at a locus.

Essentially, these VNTR's are small repeats of DNA sequence that exist in multiple copies, and the number of these repeats can vary.
Variable-number tandem-repeat (VNTR)
A locus including a tandemly repeated sequence may exhibit moderate to high levels of intraspecific variation in the alleles available for that locus.
A technique for detecting polymorphisms using VNTR core sequences as primers for PCR.

DArT (or Diversity Arrays Technology) ...
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 repeats; any gene whose alleles contain different numbers of tandemly repeated oligonucleotide sequences. Vector -- a self-replicating DNA molecule that transfers a DNA segment between host cells.
