Genetic studies on Russians

Genetic studies show that Russians are overall closely related to other Eastern European and North European populations, such as Poles, Belarusians, Ukrainians, as well as Latvians, Estonians, Lithuanians, Finns and Swedes, but also display significant genetic heterogenity, evidence for multiple genetic ancestries and admixture events. The northern group of Russians cluster close to surrounding Finno-Ugric speaking peoples.
