Repeated segments of the same sequence of multiple triplet codons, each segment varying between 14 and 100 base pairs, useful as linkage markers due to their highly polymorphic nature and the fact that they are usually situated near genes. Minisatellites are inherently unstable and susceptible to mutation at a higher rate than other sequences of DNA.
