- Genetic structure of Italian population is described as regards the level of inbreeding measured through the frequency of consanguineous marriages during a long period of time in different geographical areas.
Analyses of spatial and temporal variation of the different types of marriages between close biological relatives allow us to point out the major factors responsible for the availability of cousins to marry within a specific area: population size, fertility, mortality and migration rates and, in general the demographic structure, changing over time and greatly affected by variation in the socio-economic structure.
A deepened analysis, within each consanguinity degree, of the various pedigrees differing in the sex of ancestors, give information on the type of migration (patrilocal or matrilocal) occurred in various parts of Italy, as probable consequence of differential type of economy (for instance: pastoral or agricultural in Sardinia). Moreover, a cultural factor of varying intensity could be recognised in the greater observed frequency of marriages in which the nearest ancestors are females, interpreted as a tendency to maintain family ties by mothers of consanguineous mates.

- Abstract
- Genetic structure of Italian population is described as regards the level of inbreeding measured through the frequency of consanguineous marriages during a long period of time in different geographical areas. Analyses of spatial and temporal variation of the different types of marriages between close biological relatives allow us to point out the major factors responsible for the availability of cousins to marry within a specific area: population size, fertility, mortality and migration rates and, in general the demographic structure, changing over time and greatly affected by variation in the socio-economic structure. A deepened analysis, within each consanguinity degree, of the various pedigrees differing in the sex of ancestors, give information on the type of migration (patrilocal or matrilocal) occurred in various parts of Italy, as probable consequence of differential type of economy (for instance: pastoral or agricultural in Sardinia). Moreover, a cultural factor of varying intensity could be recognized in the greater observed frequency of marriages in which the nearest ancestors are females, interpreted as a tendency to maintain family ties by mothers of consanguineous mates.
