Miss Iceland wins Miss World! Now, of course, the title is kind of a joke, because she looks a bit different than Miss Sweden or Miss Denmark, though not as exotic as Miss Norway. In fact, though it is surely seeing what you want to see, she seems to resemble Shannen Doherty or one of the Corrs sisters. This is post facto observation, as there is evidence of Irish admixture in this one Nordic nation.

Update: While doing a little research I found out that Miss Thailand, Sindee Jensen, has a Danish father! What's up with the Siam-Scandinavian combination?

Update II: Dienekes has a post on Norwegian Y chromosomes.
