Population genetic characteristics were estimated in the Alatyr' raion (administrative district) of the Republic of Chuvashia, which has long been populated by three ethnic groups. The ethnic assortativeness values in the town of Alatyr' and the rural area of the district were 1.17 and 1.21, respectively, for Russians; 1.14 and 4.82, respectively, for Chuvashes; and 1.33 and 2.45, respectively, for Mordovians. Wright's statistics were as follows: Fst = 0.00358, Fit = 0.00178, and Fis = 0.00134. The migration indices were 0.0264 for Alatyr' and 0.0178 for the district. The endogamy indices for the total and the Russian populations of Alatyr' were 0.47 and 0.53, respectively. The parameters of isolation by distance were a = 0.000189 and b = 0.00959 for the urban and a = 0.000318 and b = 0.00919 for the rural area. Schemes of the genetic landscape were constructed. The influence of the polyethnic composition on the genetic structure of the population is discussed.
对楚瓦什共和国阿拉蒂尔区（行政区）的人口遗传特征进行了评估，该地区长期以来一直居住着三个民族。在阿拉蒂尔镇和该地区农村，俄罗斯人的族内结婚比率分别为1.17和1.21；楚瓦什人的族内结婚比率分别为1.14和4.82；莫尔多瓦人的族内结婚比率分别为1.33和2.45。赖特统计数据如下：Fst = 0.00358，Fit = 0.00178，Fis = 0.00134。阿拉蒂尔镇的迁移指数为0.0264，该地区的迁移指数为0.0178。阿拉蒂尔总人口和俄罗斯人口的近亲结婚指数分别为0.47和0.53。城乡距离隔离参数分别为：城市地区a = 0.000189，b = 0.00959；农村地区a = 0.000318，b = 0.00919。构建了遗传景观图，并讨论了多民族构成对人口遗传结构的影响。
