Electrophoresis of blood proteins was used to determine, for the first time, the level of genetic variability of certain loci in the sable (Martes zibellina L.,). Variation of 23 blood proteins encoded by 25 genes was analyzed. Polymorphism was revealed in six genes. The level of heterozygosity was estimated at 0.069; the proportion of polymorphic loci was 24%. Data on the history of the sable population maintained at the farm, on geographical distribution of natural sable populations, and on the number of animals selected for reproduction in captivity is presented. The great number of animals studied and the extensive range of natural sable populations, on the basis of which the population maintained in captivity was obtained, suggest that the results of this work can be used for estimating the variability of the gene pool of sable as a species.
首次运用血液蛋白电泳法测定紫貂（Martes zibellina L.）某些基因座的遗传变异水平。分析了由25个基因编码的23种血液蛋白的变异情况。在6个基因中发现了多态性。杂合度水平估计为0.069；多态性基因座的比例为24%。文中还给出了养殖场紫貂种群的历史数据、自然紫貂种群的地理分布数据以及圈养繁殖所选动物的数量。鉴于所研究动物数量众多，且圈养种群源自广泛的自然紫貂种群，表明这项工作的结果可用于评估紫貂作为一个物种的基因库变异性。
