Three samples of surnames reported in the telephone directory of Cosenza province, Italy, are used, singly and together, to detect the presence of genetic barriers and to analyze the genetic relationship between the Italian and the Italo-Albanian communities living in this area. The genetic structure of the population seems characterized by the distinction between the northern and southern regions of the province. The Sibari plain, endemic with malaria until recently, probably constituted a genetic barrier. In the southern region of the province, the valley along the Crati river (also occupied by malarial fenlands), constituted a genetic barrier between the northern Sila upland and the western coast. Surname similarities between Italians and Italo-Albanians could be the result of gene flow and/or an initial choice of similar surnames; the second possibility accords with the persistence of the Albanian cultural identity and the level of endogamy in Albanian communities. In fact, the coefficient of relationship by isonomy (Ri), which is significantly higher in Italo-Albanians than in Italians, may be the result of genetic isolation and endogamy.
我们使用了意大利科森扎省电话簿中报告的三个姓氏样本，单独使用以及综合使用，以检测遗传屏障的存在，并分析居住在该地区的意大利人和意大利 - 阿尔巴尼亚人群体之间的遗传关系。该人群的遗传结构似乎以该省北部和南部地区的差异为特征。直到最近仍流行疟疾的锡巴里平原可能构成了一个遗传屏障。在该省南部地区，克拉蒂河沿岸的山谷（也有疟疾沼泽地）构成了锡拉高地北部和西海岸之间的遗传屏障。意大利人和意大利 - 阿尔巴尼亚人之间姓氏的相似性可能是基因流动和/或最初选择相似姓氏的结果；第二种可能性符合阿尔巴尼亚文化身份的持久性以及阿尔巴尼亚社区内婚制的程度。事实上，同宗关系系数（Ri）在意大利 - 阿尔巴尼亚人中明显高于意大利人，这可能是遗传隔离和内婚制的结果。
