RESUMO
Allele frequencies for the high polymorphic short tandem repeats (STR) loci PentaE, PentaD, D18S51, D21S11, TH01, D3S1358, FGA, D16S539, D7820, D13S317, vWA and D81179 were analysed in an native Amerindian population from Mato Grosso do Sul state named Terena. Deviations from Hardy-Weinberg expectations were evaluated and the results showed no differences from equilibrium in all loci. The combined power of discrimination and the combined power of exclusion for the 12 tested STR loci were 0.99999999 and 0.999999 respectively. The Terena population data were compared to other from 11 Brazilian populations (Amazônia, Pernambuco, Mato Grosso do Sul, São Paulo, Rio Grande do Sul, Alagoas, Sergipe, Rio Grande do Norte, Santa Catarina, Rondônia and Rio de Janeiro) representing the major Brazilian geographic regions. The F(ST) comparative analysis showed no significant differences between all those populations except when comparing Terena with the remained ones.
