Sažetak
Population genetic structure of an isolated island population was determined by high-resolution analysis of mtDNA diversity. Analyses of polymorphisms in HVS I, HVSII and in coding region of mtDNA were performed in a sample of 169 individuals from 8 villages of the Island of Hvar (Adriatic Sea, Croatia). All typical European mtDNA haplogroups were found ; the most frequent ones were H (24.85%) and U (23.67%). Haplogroup H, although significantly underrepresented comparing to other Croatian and European populations, shows high diversity comprising of more than 10 subhaplogroups with many different haplotypes, which implies to its older age of ancestry. Similarly, haplogroup U, especially branch U5, shows quite high number of lineages. However, influence of genetic drift in this isolated population can be seen in considerably elevated frequencies of particular lineages in (sub)haplogroups F, I, U2e, U5b1 and T2h. Especially interesting is presence of haplogroup F of Asian origin in 5 out of 8 villages, reaching total frequency of 6.51%. The finding of haplogroup I in 5.33%, presented by lineage with rare backmutation, is also unusual. Comparing to other Croatian islands the Island of Hvar shows higher diversity of mtDNA lineages and somewhat lower impact of genetic drift in shaping the observed genetic diversity of mtDNA. This could be explained by several immigratory episodes of genetically quite distant populations that shaped the current population of the Island of Hvar.
