According to a 2014 admixture analysis of Western Balkan, the South Slavs show a genetic uniformity. Bosnians and Croatians were closer to East European populations and largely overlapped with Hungarians from Central Europe. In the 2015 analysis, Bosnians and Croatians formed a western South Slavic cluster together with Slovenians, in opposition to an eastern cluster formed by Macedonians and Bulgarians, with Serbians in between the two. The western cluster has an inclination toward Hungarians, Czechs, and Slovaks, while the eastern ones leans toward Romanians and, to some extent, to Greeks. The modeled ancestral genetic component of Balto-Slavs among South Slavs was between 55 and 70%. In the 2018 analysis of Slovenian population, the Slovenian population clustered with Croatians, Hungarians and was close to Czech.
