The genetic consequences of population differentiation and isolation have been the subject of conservation biology. In this study, we analysed the genetic diversity and structure of Mongolian sheep in China. These animals belong to a traditional local breed with high production, extensive adaption, early maturity and roughage resistance. For this purpose, 26 microsatellites were genotyped for five Mongolian sheep populations. The Bayesian clustering indicated five clusters as the most probable genetic structure of the populations investigated. In addition, a clear genetic structure was revealed in three populations distributed at large geographical scales, while the other cluster encompassed UQ and HLBR sheep that displayed no clear differentiation, probably due to their close and small geographical distributions. Overall, our results are helpful in understanding the interplay of population dynamics in these close genetic lineages of Mongolian sheep.
种群分化和隔离的遗传后果一直是保护生物学的研究主题。在这项研究中，我们分析了中国蒙古羊的遗传多样性和结构。这些动物属于一种传统的本地品种，具有高生产性能、广泛的适应性、早熟和耐粗饲料的特点。为此，对五个蒙古羊种群的 26 个微卫星进行了基因型分析。贝叶斯聚类分析表明，五个聚类是调查种群最可能的遗传结构。此外，在三个分布在大地理尺度上的种群中显示出明显的遗传结构，而另一个聚类包含 UQ 和 HLBR 羊，它们没有明显的分化，这可能是由于它们的地理分布接近且较小。总的来说，我们的研究结果有助于了解蒙古羊这些近缘遗传谱系中种群动态的相互作用。
