| Abstract: | Using polymerase chain reaction (PCR), TaqI polymorphism for the D2 dopamine receptor gene (DRD2) was studied in eight populations of the Volga-Ural region that belong to the Turkic (Bashkirs, Tatars, and Chuvashes), Finno-Ugric (Maris, Komis, Mordvinians, and Udmurts), and Eastern-Slavonic (Russians) ethnic groups. Significant differences in the distribution of genotype frequencies were found between the Tatar population belonging to the Turkic branch of the Altaic linguistic family and the Mari and Mordvinian populations belonging to the Finno-Ugric branch of the Ural family and between the Tatar and Bashkir populations belonging to the Turkic ethnic group. |
