RESUMO
Allele frequencies for 15 short tandem repeat (STR) loci were obtained from a sample of 12,030 individuals undergoing paternity testing. This sample includes individuals from all States in Brazil, combined according to the current country division into five regions (North, Northeast, Central West, Southeast, and South). The most polymorphic loci were D2S1338 and D18S51. All the analysed loci meet Hardy-Weinberg equilibrium expectations. Combined power of discrimination and combined power of exclusion for the 15 tested STR loci were 0.999999999999990 and 0.9999992, respectively. Comparative analysis between populations from different Brazilian macroregions as well as between Brazil and other relevant populations are presented.

Allele frequencies for 15 short tandem repeats (STR) loci were obtained from a sample of 4076 unrelated individuals undergoing paternity testing. The population is from Paraná, Southern Brazil. The loci are the most commonly used in forensic and paternity testing, being analyzed by the AmpFlSTR((R)) Identifiler (Applied Biosystems) commercial kit. The most polymorphic loci were D2S1338 and D18S51. Excepting the D13S317, all loci were in Hardy-Weinberg equilibrium. Comparative analyses between our population data and other populations are presented.
