Hypervariable sequence: A  segment of a chromosome characterised by considerable variation in the number of tandem repeats at one or more loci . Hypervariable locus: A locus  with many alleles; especially those whose variation is due to variable numbers of tandem repeats . Hypervariable region (HVR) : A chromosomal segment characterized by multiple alleles within a population for a single genetic locus .
