Estimation of Inbreeding, Kinship and Genetic Distances from Surnames – Coastal Population of Middle Dalmatia, Croatia
A. Malnar
Abstract
This work was dedicated to the investigation of the population structure of the middle
Dalmatia settlements: Jesenice, Mimice, @ivogo{}e and Zaostrog by surname distribution
study and applying the isonymous method. The surnames of males and females
in marital pairs were analyzed as well as of their first and second-generation ancestors
on the sample of a total of 3,024 examinees. The analyses of surnames pointed to the
rates of inbreeding, kinship and genetic distances of the populations. Although the values
of the inbreeding coefficient are high in all the four settlements, the inbreeding coefficient
is exceptionally high in Mimice. A total kinship coefficient for the four settlements
speaks also in favor of the high rate of kinship in the examined settlements, i.e. of
the high rate of the reproductive isolation of the whole region during the analyzed period.
The reasons for such high coefficients are natural features of the examined region
(the mountains of Mosor, Biokovo and Rili}), poor traffic connection of this region in the
past, the patrilineal mode of inheritance and the demographic specifics of the population.
The matrix of genetic distances between examined settlement pairs reveals that
Mimice, a settlement with the highest share of isonymous marriages, shows the greatest
distances in comparison to the other settlements. On the other hand, Jesenice, @ivogo{}e
and Zaostrog are characterized by small genetic distances, which is the fact that speaks
in favor of their genetic homogenization and »openness« toward interpopulational migrations,
i.e. the gene flow.
