Since my last call for more participation from the Balkans, I was able to create a new Bulgarian_D sample of 5 participants. Together with the Greek_D sample, the Balkans_D sample of non-Greek, non-Bulgarian project members, the Behar et al. (2010) Romanians, and the Xing et al. (2010) Slovenians (the latter on a smaller number of markers), we are beginning to get a better feel of genetic variation in the Balkans. There have been several other averages that have been adjusted with more participation; all of them can be seen in the Dodecad v3 spreadsheet.
The table below shows the major components (>1%) in the available Balkan populations.
The Bulgarian average as it stands seems reasonably close to the Romanian one, and is characterized by balanced West/East European components; in this balance it resembles Greeks, who, however, have lower levels of both components and higher levels of the Mediterranean/West Asian/Southwest Asian components.
Slovenians contrast with Hungarians in having reverse West/East European levels, and with their neighboring Italians in having quite a bit more of the East European component, and quite a bit less of the Mediterranean one. Bulgarians/Romanians contrast with Slavic groups from eastern Europe in having less East European and more Mediterranean/West_Asian.
Hopefully before long, more participation from the western/central Balkans (Serbs, Croats, Bosnians, Montenegrins, Albanians, Slav Macedonians) will allow us to fill more holes in our understanding of the genetic landscape of Southeastern Europe.
