Sažetak
Croatian islands are examples of genetic isolates, with low level of heterozygosity and high level of inbreeding due to endogamy, but also due to ethnohistory, biological characteristics, migrational patterns, and ecological and sociocultural environments. Such small communities can reflect large demographic processes that happened in human prehistory and history and give us insight into the ancient migratory routes and the formation of Croatian and Southeast European gene pool. The aim of this study was to evaluate the level of isolation of an insular population from the island of Lastovo in the Dubrovnik archipelago, based on the observed mitochondrial and Y chromosome haplogroup distribution. We analyzed 51 mtDNAs and 12 Y chromosomes to observe the differences and similarities in the maternal and paternal landscapes of the island. The observed haplogroups are considered to originate from Neolithic times, when the Island served as an important point on the sailing routes connecting the western and eastern coast of the Adriatic. Lastovo was in complete isolation for 500 years during the period of Dubrovnik Republic, when evolutionary forces and practice of consanguinity affected the demography of the island. Based on both mtDNA and Y chromosome markers, Lastovo showed elevated frequencies of certain subclades, most probably as a result of genetic drift, which makes the island a great outlier when compared to other Croatian populations.
