... -- This technique takes advantage of a suite of restriction enzymes,2 which can 1 Also known as DNA fingerprints, these are highly variable DNA sequences that occur in short repeats, such as GAGAGAGAGA. The number of repeats can vary from a few to over 30 so it is possible to have many variants at this hypervariable region.

... 3 Phylogeography focuses on the geographic distribution of genetic variation, usually at the level of species and genera. Phylogeographic studies often reveal molecular evolutionary separations below the species level, as is the case with green turtles ( Chelonia mydas; Bowen et al., 1992)
