Native American ancestry proportions in the Quebec regions.

Here Quebec regional/ethnocultural groups are presented with (number of individuals with genotype data; number of individuals with genealogical data). For each population, expected Native American genetic contribution was estimated using genealogical data. The Native American ancestry proportions in the Quebec subpopulations was estimated with 1) the ADMIXTURE software [43] 2) the HAPMIX software [39], and 3) IBD sharing analysis using the fastIBD software [41]. For each measure, we tested for differences among subpopulations using a Kruskal-Wallis test (Table S3).本研究呈现了魁北克各区域族群与族裔群体的相关数据，括号内依次标注为携带基因型数据的个体数量、携带谱系数据的个体数量。针对每一个种群，研究人员借助谱系数据估算了其预期的美洲原住民遗传贡献比例。本研究通过三种途径估算魁北克亚群的美洲原住民祖先血统占比：1）ADMIXTURE软件[43]；2）HAPMIX软件[39]；3）基于fastIBD软件[41]的血缘同一性（Identity-by-Descent, IBD）共享分析。针对每一种估算方法，研究人员采用克鲁斯卡尔-沃利斯检验（Kruskal-Wallis test）对各亚群间的差异开展显著性检验，相关结果详见补充表S3。
