Holistic approach in the study of population structure based on the analyisis of serogenetic polymorphisms (the Island of Krk, Croatia)

The population structure of the northern Adriatic island of Krk (six rural villages), Croatia, was studied using six red blood cell enzyme and serum protein loci. Allele frequencies were used to compute genetic distances (E2) after which a model-free approach (distance matrix correlations) was employed. The studied rural communities revealed isolation (endogamy rate of 87, 6) and clusterisation in to two groups, which coincides with known ethnohistorical events and contemporary migrational data. Spearman R correlation coefficient between genetic and geographic distances (r=0, 05) and genetic and linguistic distances (r=0, 143) are not significant, in contrast with genetic distances and migration kinship (-0, 599) is a significant correlation. The results indicate bio-cultural and socio-cultural events, rather than geographical distances, to be the primary determinants of anthropogenetic structure of the studied island population groups. The contribution of serogenetic polymorphisms analysis to holistic anthropological apprehension of human (micro)evolutionary processes in contemporary European populations is discussed.
