Abstract

Endogamy and gametic indices for both Russian and Adyg populations living in the Adyg autonomous region of Krasnodar district were determined on different levels of territorial units: village, rural, community (a group of villagers) and rural region. Inbreeding coefficient was estimated for Adyg population and its structure analysed: a random component contributes mostly to the inbreeding coefficient (Fst = 0.00991), non-random component of the inbreeding coefficient being Fis = 0.010009, which testifies to negative marital assortativity among Adygs. Local inbreeding "a" and decline in the inbreeding "phi" coefficient at a distance from 0 to 500 km were calculated using the Malecot's formula: the coefficient "a" was found to be 0.00397, which is in good accordance with the Fst.

摘要

对生活在克拉斯诺达尔地区阿迪格自治区的俄罗斯人和阿迪格人在不同层级的地域单位(村庄、乡村、社区(一群村民)和乡村地区)确定了近交系数和配子指数。对阿迪格人群体估计了近亲繁殖系数并分析了其结构:近亲繁殖系数的随机成分贡献最大(Fst = 0.00991),近亲繁殖系数的非随机成分Fis = 0.010009,这证明阿迪格人之间存在负向婚姻选型。使用马勒科特公式计算了局部近亲繁殖“a”以及在距离从0到500公里处近亲繁殖“phi”系数的下降:发现系数“a”为0.00397,这与Fst非常吻合。
