Guizhou province in southwest China has abundant genetic and cultural diversities, but the forensic features and genetic structure of Guizhou populations remain poorly understood due to the sparse sampling of present-day populations. Here, we present 30 insertion/deletion polymorphisms (InDels) data of 591 human individuals collected from four populations, Dong, Yi, Han, and Chuanqing residing in Guizhou. We calculated the forensic parameters of 30 InDel loci and found that this panel meets the efficiency of forensic personal identification based on the high combined power of discrimination, but it could only be used as a complementary tool in the parentage testing because of the lower combined probability of exclusion values. The studied populations are genetically closer related to geographically adjacent or linguistically related populations in southern China, such as the Tai-Kadai and Hmong-Mien speaking groups. The unrecognized ethnic Chuanqing people show an additional genetic affinity with Han Chinese, highlighting the role of possible military immigrations in their origin.
中国西南部的贵州省拥有丰富的遗传和文化多样性，但由于当代人群样本稀少，贵州人群的法医特征和遗传结构仍知之甚少。在此，我们展示了从居住在贵州的侗、彝、汉、穿青四个群体收集的591名个体的30个插入/缺失多态性（InDels）数据。我们计算了30个InDel位点的法医参数，发现该面板基于高联合鉴别力满足法医个人识别的效率，但由于较低的联合排除概率值，它只能作为亲子鉴定的补充工具。所研究的群体在遗传上与中国南方地理上相邻或语言相关的群体更为接近，如说侗台语和苗瑶语的群体。未被识别的穿青人群体与汉族表现出额外的遗传亲和力，突出了可能的军事移民在其起源中的作用。
