Allelic frequency distribution of 17 STRs from Identifiler and PowerPlex-16 in Central Portugal area and the Azores archipelago

Abstract This study analyzes the allelic frequency distribution of 17 STRs contained in the AmpF l STR Identifiler (Applied Biosystems) and PowerPlex16 System (Promega) commercial kits for two large population samples from the Azores archipelago (Portugal) ( N  = 475) and from Central Portugal ( N  = 2125). Likewise, it includes a comparative study among the population groups analyzed in this paper and those which history points out as originating from the first settlers of the Azores. All loci were highly polymorphic. The Central Portuguese area and the Azores archipelago population samples are in Hardy–Weinberg equilibrium for the 17 markers analyzed.
