Abstract (EN): Two Native American populations from North and northwest regions of Argentina (Toba and Colla) were analyzed for 17 Y chromosome short tandem repeat loci (Y-STRs), namely, DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4.1. Over 357 allele transfers, two one-step mutations could be detected at DYS456 and GATA H4.1 loci. A new 16.1 'micro-variant' allele was observed for DYS395, characterized by an insertion at the fifth GAAA repeat. We also observed two alleles at the DYS448 locus in three samples (two from Toba and one from Colla). A total of 34 and 16 different haplotypes were detected for Toba and Colla, respectively, the former with a haplotype diversity value of 0.9769 +/- 0.01, whereas 0.9497 +/- 0.02 for the latter. Significant population differences were observed between Colla and Toba, at least in part, due to a more prevalent European input in the Colla. In agreement with this observation is the fact that the genetic distances between Colla and Iberian populations are lower than those observed between Iberian and any other Native American population. The results of multiscaling dimensional analysis and genetic distances (Rst) among Native American population samples also reflect this fact. The data show the existence of clear population stratification in the Argentina, a fact that should be taken into account in forensic casework.
