Population genetic data of the AmpFℓSTR® Identifiler® Plus and PowerPlex® 16 HS STR loci in four Canadian populations

Abstract

Allele frequencies and forensically relevant population statistics were estimated for the short tandem repeat (STR) loci of the AmpFℓSTR® Identifiler® Plus and PowerPlex® 16 HS amplification kits, including D2S1338, D19S433, Penta D, and Penta E, for three First Nations Aboriginal populations and for Caucasians in Canada. The cumulative power of discrimination was ≥ 0.999999999999984 and the cumulative power of exclusion was ≥ 0.999929363 for both amplification systems in all populations. No significant departure from Hardy-Weinberg equilibrium was detected for D2S1338, D19S433, Penta D, and Penta E or the 13 Combined DNA Index System core STR loci after correction for multiple testing. Significant genetic diversity was observed between these four populations. Comparison with published frequency data for other populations is also presented.
