24 Y-STR loci were analyzed in 223 Altay Hui individuals and 209 Altay Kazakh individuals. Haplotype diversity (HD) and discrimination capacity (DC) values were calculated. Population pairwise genetic distances (Rst) were evaluated in AMOVA analysis and compared between two studied populations and other populations. The relationships between populations were visualized through multidimensional scaling (MDS) and neighbor-joining (NJ) tree. The results indicated higher discrimination power in the Altay Kazakh and Hui populations. The Altay Kazakh was the most distantly related to Xishuangbanna Dai, while Altay Kazakh was the most closely related to Gansu Kazakh. The results may provide useful information for paternal lineages and increase our understanding of genetic relationships between two studied populations and other populations.
对223名阿勒泰回族个体和209名阿勒泰哈萨克族个体的24个Y染色体短串联重复序列（Y-STR）位点进行了分析。计算了单倍型多样性（HD）和鉴别能力（DC）值。在分子变异分析（AMOVA）中评估了群体间的遗传距离（Rst），并在两个研究群体与其他群体之间进行了比较。通过多维标度分析（MDS）和邻接法（NJ）树直观展示了群体之间的关系。结果表明，阿勒泰哈萨克族和回族群体具有较高的鉴别能力。阿勒泰哈萨克族与西双版纳傣族的亲缘关系最远，而与甘肃哈萨克族的亲缘关系最近。这些结果可能为父系谱系提供有用信息，并增进我们对两个研究群体与其他群体之间遗传关系的理解。
