Sažetak
Island of Hvar is situated in the central Eastern Adriatic, and its relatively small rural population has been reproductively isolated throughout history. Therefore, founder effects, genetic drift and inbreeding have had a significant role in the shaping of the current genetic diversity of Hvar Islanders. Island isolates are among the most suitable populations for theoretical analyses of microevolutionary processes and population differentiation. In this context, mitochondrial DNA (mtDNA) an Y chromosome studies are used to reveal demographic history, migrations, population origins and genetic structure of a population. We analyzed SNP markers of 161 mtDNAs and of 412 Y chromosomes from the island of Hvar, including STRs of 20 male islanders. Results showed a much higher number of mtDNA haplogroups (34) than Y chromosome ones (15). Haplotype diversity analysis showed low gene diversity among both mtDNAs and Y chromosomes on the island, while haplogroup distribution points to a significant population differentiation between the eastern and western part of the island. This substructure effect stems from different representation of subhaplogroups, as well as from differences between haplotypes within the same subhaplogroups and is based on specific demographic processes which occurred on Hvar during its history. When put in a wider context, haplogroups of both uniparental markers placed Hvar in the context of South- Eastern Europe, but the frequencies and the distribution of certain haplogroups significantly deviate from other SEE populations.
