“…However, remarkable differences from other Sardinian groups have been detected, especially for MNSs and ACPl systems, due mainly to high MNS*MS and ACPl*B, and low ACPl*C values in Alghero. These differences could be explained taking into account the high variability of these markers in Sardinia (Ulizzi et al, 1988;Vona et al, 1992). The ACPl*C allele frequency in Alghero, one of the lowest in Sardinia, is in agreement with the positive correlation described between this gene and altitude (Palmarino et al, 1975).…”

“…Allele frequencies found in Alghero are, in general, inside the range of Sardinian variation, sharing those Sardinian peculiarities not matched by any other population in the Mediterranean region (for a comparison with the available frequencies in Western Mediterranean, see Piazza et al, 1989a, Moral, 1986Ulizzi et al, 1988;Walter et al, 1989;Vona et al, 1992). As to blood groups, Alghero shows low ABO*A and RH*cde frequencies, and high ABO*O, RH*CDe and MN*M values, characteristic of Sardinian populations.…”

“…Among European populations, the people of the Mediterranean island of Sardinia constitute an example of genetic isolation, as demonstrated by the well-documented uniqueness of their gene frequencies (Modiano et al, 1986;Piazza et al, 1989a,b;Walter et al, 1991;Vona et al, 1992). Many studies have established numerous genetic, demographic and linguistic peculiarities of Sardinians (Griffo, 1988).…”

Data on 20 genetic polymorphisms (61 alleles) in the Algehero population on the northwestern coast of Sardinia are presented and discussed in relation to its linguistic peculiarity inside the island. Since the Aragonese (Spain) conquest of Sardinia in the 13th century, the Catalan language, the same as that spoken in Northeastern Spain and certain districts of Southern France, has been used in Alghero even until today. Analysis for heterogeneity of gene frequency distributions indicates that the genetic information obtained on Alghero is adequate to discriminate Sardinians from other neighbouring populations. Genetic variation between populations measured through genetic distances and principal-component analysis shows that the present-day population of Alghero is much closer genetically to Sardinians than to Catalonians. Our genetic results do not support any interpretation of the linguistic affinities between Alghero and Catalonia at present as indicative of biological kinship.

“…All these factors, together with prehistorical and historical events, have contributed to the remarkable genetic differentiation of Sardinians from other European and Mediterranean populations, as demonstrated by the well-documented uniqueness of some gene frequencies (Piazza et al, 1976;Vona et al, 1994;Modiano et al, 1986), and by the microgeographic heterogeneity within the island (Vona et al, 1992).…”

-For years the population of Sardinia has been object of numerous studies in the fields of anthropology and population genetics. Researches on genetic structure of Sardinian population, performed with of both classical and DNA markers, revealed an extremely complex picture of the relationships between Sardinian and other Italian and Mediterranean populations, that can be explained by Sardinian's historical and demographic past. A high degree of internal heterogeneity was also found and it can be attributed first to strict isolation and consequent high levels of endogamy and consanguinity, secondly, to selective factor linked to endemic malaria that influenced the distribution of some gene frequencies. Finally an influence on Sardinian's biological history could be attributed to the demographic events such as low population density and scant matrimonial movement, which triggered off phenomena of genetic drift.

“…An important feature of Sardinia is the high genetic heterogeneity within the island itself due to geographical andor cultural fragmentation into numerous isolates (Moroni et al, 1972;Workman et al, 1975;Vona, 1980, 1984;Piazza et al, 1985;Modiano et al, 1986;Griffo et al, 1988;Ulizzi et al, 1988;Floris-Masala et al, 1989;Gatti, 1990;Marini, 1990;Succa et al, 1990;Gruppioni et al, 1991;Walter et al, 1991;Contu et al, 1992;Vona et al, 1992;Morelli, 1993;Brasili Gualandi et al, 1994;Moral et al, 1994).…”

An interesting aspect of the island of Sardinia (Italy) is the wide range of genetic variability within the island itself. The variability is widened by the presence of some populations of different ethnic origin who speak a language other than Sardinian. This work deals with the study of the genetic structure of the Carloforte population which inhabits the tiny island of S. Pietro 4 km off the southwest coast of Sardinia. S. Pietro was first populated in 1738 by emigrants coming from the island of Tabarka (Tunisia) who spoke an archaic form of the Ligurian dialect. Data on genetic polymorphisms in the Carloforte population are presented and discussed in relation to some Sardinian and Italian populations. Data on demographic and matrimonial structure are also presented. The genetic analyses show the Carloforte population as being clearly separated from both Sardinians and continental Italians. The isolation of Carloforte, highlighted by language diversity, endogamy, and consanguinity levels and marriage area, supports the idea of genetic diversity linked to cultural peculiarity.
