Sažetak
This study presents genetic diversity and structure of contemporary Krk islanders revealed by high-resolution mitochondrial
DNA analysis on a sample of 132 unrelated autochthonous adults from seven different settlements and regions
of the island. Relatively high level of haplogroup and haplotype diversity in the overall island sample is an indicator
of numerous migrations and gene flows throughout the history. Expectedly, the results show the highest frequency of
haplogroup H (33.3%), yet this value is much lower compared to different Croatian and other European mainland populations.
An interesting finding refers to highly elevated frequencies of some haplogroups, otherwise rare in Croatia and
most of the Europe, such as I (11.3%) and W (7.6%) in Krk population, especially pronounced in some settlements. At the
level of settlements, many of the major European haplogroups were found to be absent from their mtDNA gene pools,
whereas several others show a pronounced deviation from an average. Overall, our results suggest a tangled interplay of
different evolutionary forces, such as founder effects and a few strong bottlenecks, presumably due to epidemics, which
have occurred in various periods of the island’s history. Cultural customs, such as frequent endogamy in some regions of
the island during past centuries, have additionally shaped its genetic structure into the observed present-day diversity
patterns.
