Another map and model of predicting where a person will come from in europe based on his genetics.(via) It is only based on common variations and not rare ones so the chances are that the map can be made more accurate in the future at least until the genetic pool gets more mixed up with the increasingly common sight of mixed nationality marriages (even in Finland!).

Biologists have made a genetic map of Europe which as you can see roughly resembles Europe Geographically.

The map also identifies the existence of two genetic barriers within Europe. One is between the Finns (light blue, upper right) and other Europeans. It arose because the Finnish population was at one time very small and then expanded, bearing the atypical genetics of its few founders.

A couple of things come to my mind on seeing this map. One is the surprising genetic distance between Sweden and Finland, although Finland was part of the Swedish Empire for over 400 years, suggesting that Swedish immigration over that time really was small. Also that Poland faces Finland on the map but where do the Eastern Eurpean states figure, countries like Estonia for example, and it would be really interesting to map Russia onto this too.
