A genetic study on Estonians agrees with a multivariate craniometric study (Homo. 2002;52(3):240-53.) in proposing that the Finno-Ugrians were originally a separate race from both Caucasoids and Mongoloids.

A population genetic characterization of Estonians.
This paper discusses the genetic characterization of Estonians on the basis of eight blood group systems, and the traits of PTC tasting and colour blindness in 40 Estonian population samples from various parts of the country. The allele frequencies for the total Estonian population and for the four most different regions are presented. The survey shows genetic heterogeneity within the Estonians; the greatest genetic differences were observed in West-East direction. The West-Islands, West, and North Estonia differ from the other regions (East, South-East, also South-West and Central Estonia--which form a compact cluster). The mean allele frequencies of the Estonians are comparable to those typical for populations from North and East Europe, but the allele frequencies of Estonians are characterized by tendencies in two opposite (western and eastern) directions, like in other Finno-Ugric populations and concerning other anthropological traits. Estonians reveal closest similarities to the nearest neighbouring populations, regardless of their language group. The genetic heterogeneity and antagonistic traits in Estonians seem to be traces of the original genetic structure of Finno-Ugric ancestor populations which were neither Mongoloid nor Caucasoid.
