We clarify the contribution of gene introgression in the recovery of the sable Martes zibellina, which has undergone significant population declines by the end of the nineteenth century. To verify the contribution of interspecific gene introgression, variation among the sable and the pine marten Martes martes was investigated utilizing restriction fragment analysis of the mitochondrial cytochrome b gene as a genetic markers. Evidence of symmetric introgression of mitochondrial genes between the species was detected. Frequency of marten haplotypes in the sable was 8.3%, while sable haplotype was found in 10% of the martens. The low frequency of mitochondrial DNA haplotype A indicates a comparatively low portion of the Eastern lines in the current sable populations in Western Siberia, despite the introduction of a large number of Eastern sable subspecies. These findings are of great importance for the conservation genetics of the sable. Overhunting of the sable as a more fur valuable species than the pine marten may lead to violation of the dynamic equilibrium between genetic systems of these related species. Mitochondrial markers can be used to identify genetic lines of other species or subspecies in hybrid zones.

我们弄清了基因渗入对黑貂Martes zibellina的恢复的贡献，黑貂在19世纪末已经经历了显着的种群减少。为了验证种间基因渗透的貂皮和松貂中的贡献，变异貂貂利用线粒体细胞色素b基因的限制性片段分析作为遗传标记进行了研究。检测到物种之间线粒体基因对称渗入的证据。貂的貂单倍型频率为8.3％，而貂中有10％的貂单倍型。线粒体DNA单倍型A的低频率表明，尽管引入了许多东部黑貂亚种，但在西西伯利亚当前黑貂种群中，东部品系的比例相对较低。这些发现对于黑貂的保存遗传学非常重要。将黑貂作为比貂更有价值的物种进行过度追捕可能会导致违反这些相关物种的遗传系统之间的动态平衡。
