Twelve autosomal and 8 X chromosome Alu markers were genotyped for the first time in 161 Central and West Yakuts to test their ability to reconstruct the genetic history of these populations, the northernmost Turkic-speaker ethnic group living in Siberia. Autosomal data revealed that both groups showed extremely close genetic distances to other populations of Siberian origins that occupied areas from Lake Baikal, the ancestral place of origin of Yakuts, to North Siberia, their current territories. Autosomal and X chromosome data revealed some discrepancies on the genetic differentiation and the effective sizes of Central and West Yakuts. Such discrepancies could be related to the patrilineal and occasionally polygamous structure of these populations. Autosomal and X Alu markers are informative markers to reconstruct population past demography and history, but their utility is limited by the available data. This study represents a contribution for further investigations on these populations. © 2013 E. Schweizerbart'sche Verlagsbuchhandlung, Stuttgart, Germany. Peer reviewed
