Y-STR haplotypes of Native American populations from the Brazilian Amazon region

Forensic Sci Int Genet. 2010 Oct;4(5):e121-3. doi: 10.1016/j.fsigen.2009.12.003. Epub 2010 Jan 19.


The allele and haplotype frequencies of nine Y-STRs (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS385 I/II) were determined in a sample of six native tribes from the Brazilian Amazon (Tiriyó, Awa-Guajá, Waiãpi, Urubu-Kaapor, Zoé and Parakanã). Forty-eight different haplotypes were identified, 28 of which unique. Five haplotypes are very frequent and were shared by over 10 individuals. The estimated haplotype diversity (0.9114) was very low compared to other geographic groups, including Africans, Europeans and Asians.
