Y chromosome comparative analysis of Rondônia with other Brazilian populations

Abstract In the present study, a Brazilian population, located in the Rondônia state, was genetically characterized for a set of Y chromosome specific STRs included in the Applied Biosystems kit (AmpFℓSTR®Yfiler™), which allows the simultaneous amplification of 16 markers: DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS438, DYS439, DYS437, DYS448, DYS456, DYS458, DYS635 and GATA H4. The studied population from Rondônia state, in the North of Brazil, included individuals with admixed Native American, African and European ancestry. When comparing Rondônia with other Brazilian populations no significant genetic distances were found. In the comparison with other worldwide populations, although a predominant male European influence could be detected, there were significant differences with some populations from Central and South America and Africa.
