This effect would be even more pronounced in a larger sample size. Consider how small a fraction indigenous arctic populations are of the population as a whole. In other words, larger sample sizes would be even worse off in this particular occasion.
But it is more complicated. I have Sami Heritage but it goes back to my great great grandparents. I did not know this until I started digging deeply into my ancestry, but I carry many of the polymorphisms from these people.
So although I look like a typical European Caucasian, my genetics are very untypical of that population. And this also explains my family history of heart diseases and mood disorders which are also non-typical of European Caucasians.
