@tantra129 well, sure, Alexander's Macedonians conquered a lot of territory and peoples, so if history of similar conquests is a guide, genes are spread, and mixes. Genghis Khan genes are present in 16 million individuals who have identical y-chromosomes, and some .5% of the world's population.
Why is it that we get excited when we hear that other peoples may have Alexander's (or Hellenic) genes? What difference does it make? I'm serious. Are we to believe that somehow a special something in the genes makes people special?
Anyway, I wonder what similarities exist among the people of the Balkans, and the general Mediterranean area. I wouldn't be surprised if fighting neighbors share some of the same genes.
