Genetic affinities of Estonian Poles


The Estonian Biocentre has a new genotype dataset available from the recently released "Khazar" preprint (see here). The samples include Poles from Estonia, so I ran a PCA to see whether there was a clear difference between them and their ethnic kin from Poland in terms of genome-wide genetic structure. This doesn't appear to be the case, except for a few individuals who probably have significant Estonian and/or northwest Russian ancestry. It's an interesting result, considering that, as far as I know, most Estonian Poles are not of recent Polish origin, but have roots in the East Baltic dating back to the Polish-ruled Duchy of Livonia of the 1600s. Please note, the plots were rotated and stretched horizontally to fit with geography.
