What I mean is, is there a north/south bias in the 20% gene, or an east/west bias, or some other distributional pattern that could be connected to a historical hypothesis? My own guess is that the 20% gene is spread very evenly, because the Middle Easterners became Indo-Europeans in the Ukraine staging area, and were already a hybrid group when they started conquering Europe. But I welcome anyone with facts.
