Eight STR systems (THO1, FABP, VWA, FES/FPS, HPRTB, F13A1, CSF1PO, and D6S366) were investigated in different ethnic groups of Argentina. Allele and genotype frequencies, power of exclusion, and discriminative power were investigated. Hardy-Weinberg expectations were calculated from heterozygosity levels. FST and G tests demonstrated that significant differences exist among the investigated populations for some of the eight STRs markers. The Wichi Indians are clearly separated from the Mapuche and Tehuelche, who in turn are closer to the European population, suggesting non-Amerindian admixture.
