Genetic structure of the population of Beni department (North Bolivia)

Abstract We analyze a sample of Y-chromosomes of 86 Bolivians of Beni department (Northern Bolivia). A database of Y-STRs frequencies was constructed with a total of 12 South American samples plus our population. Y-STR structure of the database reveals the degree of differentiation of our sample and the close relatedness of most of the populations considered. Differences can be due in part to the low level of admixture with European Y-chromosomes.
