Inbreeding coefficients from isonymy in the Italian-Greek villages

Abstract

There are four Italian-Greek communes in one area of Calabria and nine in an area of Apulia. The communes are too small to give good information on marital isonymy for each, but in the Calabrian area the weighted mean inbreeding coefficient and its random and non-random components are F = 0.01442, Fr = 0.00450 and Fn = 0.00997, respectively. The weighted means in the more populous Apulian area are significantly lower, F = 0.00423, Fr = 0.00379, Fn = 0.00045.
