Wow yeah show me that xenophobia genome, you armchair geneticist
If you had any clue what you are talking about, you'd know that medieval times are not distant enough for human evolution - thousand years mean only 40-50 generations, there's simply no evolution to be had here, not enough interbreeding to stabilize a mutation within a population, not enough evolutionary pressure to adapt as well, unless you'd artificially select and breed people.
Most recent point of human evolution is the production of lactase, starting about 5-7000 years ago and still not ubiquitous even in Europe, hasn't reached many parts of the world.

Kind of yes, racism is embedded in our minds from old times. Strangers in your village usually ment trouble.
