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.
