Anthropogenetic structure in Eastern Adriatic - analysis of serogenetic polymorphisms

Allele frequencies of three enzymes and three protein loci (ACP, EstD, PGM and HP, PI, TF) were determined in six rural populations of the northern Adriatic island of Krk, Croatia. Allele frequencies were used to compute genetic distances (E) after which a model-free approach (distance matrix correlations) was employed. The studied rural communities revealed an isolation (endogamy rate of 87, 6) and clusterisation in two groups which coincides with the known ethnohistorical events and contemporary migrational data. Spearman R correlation coefficients between genetic and geographic distances (R=0, 05), and genetic and linguistic distances (R=0, 143) are not significant, in contrast to genetic distances and migration kinship (R=-0, 599) where there is a significant correlation. The results indicate biocultural and sociocultural events, rather than geographical distances, to be the primary determinants of the anthropogenetic structure of the studied island population groups. The contribution of serogenetic polymorphism analysis in the holistic anthropological apprehension of human (micro)evolutionary processes in contemporary European populations is discussed.
