Autosomal and X chromosome Alu insertions in Bolivian Aymaras and Quechuas: two languages and one genetic pool.

摘要: Thirty-two polymorphic Alu insertions (18 autosomal and 14 from the X chromosome) were studied in 192 individuals two Amerindian populations of Bolivian Altiplano (Aymara Quechua speakers: main Andean linguistic groups), to provide relevant information about their genetic relationships demographic processes. The objective was determine data whether expansion language into Bolivia could be associated with (Inca migration Quechua-speakers Peru Bolivia) or cultural (language imposition by Inca Empire) Allele frequencies used assess between these groups. Our results indicated that samples showed a high similarity for both sets markers clearly differentiated Peruvian available literature. Additionally, our compared literature structure, East–West differentiation South America. close relationship suggests took place without any important contribution. Moreover, no clear geographical structure found variation among Amerindians. Am. J. Hum. Biol., 2010. © 2009 Wiley-Liss, Inc.
