The aim of our work is to reconstruct the population-genetic aspects of ethnogenetic processes in Western Siberia using a paleogenetic study of a diachronic model that includes representative series of samples from all major groups of the medieval West Siberian Data on the features of the genetic composition (at the level of diversity of mitochondrial DNA and Y-chromosome variants) of populations from the Baraba forest-steppe, Upper and Middle Ob region dated by the different parts of the Middle Ages, as well as by modern times, have been obtained. Diachronic analysis made it possible to identify the components of the gene pool that mark the genetic succession of different medieval populations, as well as with previous regional groups, as well as to identify genetic components that mark changes in the genetic composition of the population as a result of migration processes and ethnocultural interaction. The specifics of predominantly Turkic-speaking, Ugric and Samoyed (according to archaeological data) populations, as well as groups of mixed origin, were determined. The directions and geographical localization of main zones of interpopulation contacts in different Middle Ages periods were determined. An extensive data bank has been formed, including detailed archaeological, anthropological and paleogenetic characteristics of the materials included in the diachronic model under study. Our study completes the process of forming an representative diachronic paleogenetic model that covers all the main populations of the southern regions of Western Siberia over the past ~ 10 thousand years.
