Updated Eurogenes K13 at GEDmatch


The old Eurogenes K13 has been replaced by a new model with different, and hopefully more robust, ancestral clusters. The new version also includes Oracles as well as 2D and 3D Principal Component Analyses (PCA). The K13 population averages and genetic (Fst) distances between the inferred ancestral clusters are available here and here, respectively.

Thus, Eurogenes now has four tests at GEDmatch with Oracles: the Jtest, EUtest, EUtest V2 and the K13. It's useful to keep in mind that these tests will differ in their interpretation of the data, and perhaps accuracy, depending on the ancestry of the user. For instance, the new K13 should be more useful for Central and South Asians than any of the others, because it features new reference samples relevant to them.
