Yes, I sent to Maciamo the data of study of Regueiro et al. This study brought together data from all previous relevant studies from the Balkans and beyond.
MDS scaling that authors performed is very interesting. Croats and Slovenes are very close and they are closed to Ukrainians. On the other hands Serbs and Upper Macedonians (Macedonians from former Yugoslav Republic, not Aegean Macedonians) are very close. They are between Greeks and Tosk Albanians (who are close with non Balkans peoples Tajikistanis and Anatolians) and Bosniacs (who are specific and distant from the other, the closest Serbs and Upper Macedonians. Geg (Kosovo) Albanians are far and close to North East Africans (who have not shown) and Lebanese.
Slovenes and Croats are closest Slavs. On the other hand Serbs and Upper Macedonians, and slightly less Bosniacs are more Balkans. It is not surprise for me, I knew that Serbs and Upper Macedonians are closest because they are are in the center of Balkans and carriers of the same haplogroups followed natural and logical way Vardar-Morava-Danube. I supposed that Bosniacs can not be too far from the Serbs and Upper Macedonians, but they are specific. Because of natural terrain was less interference among the Bosniacs with carriers haplogroups from the South, and from the North. For me is little surprise that Slovenes and Croats are so close, because of impact on Croats by Serbs and Bosniacs, maybe it is because Croats are the most densely settled near the Slovenian border.
It is clear that Ukrainians are mostly associated with Southern Slavs (so it was assumed most, especially with the Slovenes and Croats), but there are opinions that terms Southern Slavs is no appropriate given that more reflect the linguistic link and less origin. Of course it is debatable.
