Genetic analysis of six communities of Mbyá-Guaraní inhabiting Northeastern Argentina by means of nuclear and mitochondrial polymorphic markers

Autosomal STRs, Y-chromosome markers, and mitochondrial DNA sequences were investigated in six Mbyá-Guaraní villages (Fortín M'Bororé, Yryapu, Tabay, Kaaguy Poty, Jejy, and Yaboti), all of them settled within the province of Misiones, northeastern Argentina. One hundred twenty-one unrelated ind...

One hundred twenty-one unrelated individuals were analyzed.

All autosomal STRs were in Hardy-Weinberg equilibrium. The four major native American mtDNA haplogroups were represented in the sample. Haplogroups A2 and D1 exhibited the highest frequencies (40.5% and 36.0%, respectively), and haplogroups B2 and C1 appeared to be less frequent (17.5% and 6.0%, respectively). The native American haplogroup Q1a3a was observed in a relevant proportion (88.8%). In addition, a nine-STR Y-chromosome haplotype (DYS19*13, DYS389I*14, DYS389II*31, DYS390*24, DYS391*11, DYS392*14, DYS393*11, DYS385A*14, DYS385B*16) exhibited a frequency of more than 36%. Our results indicate that the analyzed Argentinean Guaraní individuals are genetically more closely related to Guaraní from Brazil [genetic distance (.μ)2 = 0.48] than to other related tribes that are geographically closer. Statistical approaches based on autosomal data do not support the hypothesis of genetic drift previously proposed; however, this apparent discrepancy might be due to the lack of sensitivity of the autosomal markers used here. © 2010 Wayne State University Press.
