Color codes: South-Western Europe (blue), the Balkans (yellow) and the Levant (green). Error bars represent standard deviations calculated on the basis of 10,000 bootstraps.

Sicily has little I or R1a if any

Balkans meaning Greece?

Serbia, Bosnia, Phokaia, Smyrna, Northern Greece, Slovenia

[Kelmendasi]

Serbia, Bosnia, Phokaia, Smyrna, Northern Greece, Slovenia

Albania as well, since the Arbereshe settled there?

Then most have to be from northern Greece since Greeks colonized it. How else would they get it? What other Balkanites went there?

the links to the balkans could be more ancient, but I think the data points to Illyrian and Greek colonization, both ancient and modern.Besides some ancient anatolian haplogroups could have been counted as balkan imo.
