There are more studies on genetics of the people in the Balkans peninsula. Too bad I can't find the results of DNA tests on iGenea site anymore. Seems it is not available there.
However, there is a discussion at iGenea Forum - Bosnia,
and also another study - "The peopling of modern Bosnia-Herzegovina: Y-chromosome haplogroups in the three main ethnic groups" - from U.S. National Library of Medicine, National Institutes of Health.
What these results show is quite interesting. Today's nations in the Balkans region (and probably most other places on Earth) are based on religion, mostly, as well as some characteristics of societies from 19th century, like language, customs, appearance, history, etc.
