bottleneck populations
I noticed in the original entry of a blog on the J-test (not this site) the creator of J-test made a comparison of Jewish and Finnish populations: When using calculators for either group, false readings could occur because what each test is picking up are the genetic influences of the various founder groups that make up Jews (or Finns) and not necessarily strong indications of a Jewish (or Finnish) background. He gave the example of significant amount of Finnish genes showing up in Danish and Norwegian populations, which he believed to be "unexpected."
I for one, fully expect to see evidence of Finnish genes in a Norwegian person, and I am basing that on Scandinavian settlement history.
Any thoughts on this, as it relates to the population of interest in the J-test: Ashkenazi Jews?
