We investigated the genetic differentiation of five X-chromosome STR markers among five native South American Amerindian populations inhabiting three different areas of the Gran Chaco: Mocoví, Chorote, Wichí, Lengua, and Ayoreo. The observed genetic structure showed correspondence with geographic distribution more clearly than previous information obtained from autosomal STRs for the same samples. On the other hand, X-chromosome STR data did not agree with linguistic affinities. These markers proved to be informative for the study of the native populations of the Gran Chaco region.
我们研究了居住在大查科地区三个不同区域的五个南美原住民印第安人群体（莫科维人、乔罗特人、维奇人、伦瓜人及阿约雷奥人）中五个X染色体短串联重复序列（STR）标记的遗传分化情况。与之前从相同样本的常染色体STR获得的信息相比，观察到的遗传结构与地理分布的对应关系更为清晰。另一方面，X染色体STR数据与语言亲缘关系并不一致。这些标记被证明对大查科地区原住民群体的研究具有参考价值。
