The population of Campobasso Province shows a level of inbreeding that is d
istinct from most Italian rural populations, regardless of their geographic
location (F-r=0.0040; F-n=00102; F-t=0.0142). The genetic structure of the
Italian-Greek communities of Lecce and Reggio Calabria Provinces does not
appear to be affected by ethnicity. The level of inbreeding in Italian-Gree
ks of Reggio Calabria Province is similar to other Italians of Campobasso P
rovince (F-r=0.0041; F-n=0.0127; F-t=0.0168). The Italian Greeks of Lecce P
rovince show random mating, and their inbreeding is in fact very low (F-r=0
.0038; F-n=0.0024; F-t=00062).
