A sample of 203 Brazilian males from Rio Grande do Sul (RS), the Brazilian southernmost state, was typed for 11 Y-STR markers (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, and DYS439). We also typed 42 individuals from two South Amerindian tribes (Kaingang and Guarani) to use the data as parental Amerindian contribution to our analyses. Gene and haplotypic diversities were estimated, with the South Amerindian samples showing smaller values for these parameters than Brazilians. To obtain a more comprehensive picture of the genetic structure of the Brazilian population as a whole, the Y-STR data from the RS sample was compared with those already published. No genetic substructuring was observed in the comparisons performed. Multidimensional scaling confirmed the proposed European source of most Y-chromosome Brazilian patrilineages.
对来自巴西南部最南端的南里奥格兰德州(RS)的203名巴西男性样本进行了11个Y染色体短串联重复序列(Y-STR)标记(DYS19、DYS389I/II、DYS390、DYS391、DYS392、DYS393、DYS385、DYS437、DYS438和DYS439)的分型。我们还对来自两个南美印第安部落(卡因冈和瓜拉尼)的42个人进行了分型,以便将这些数据作为美洲印第安人对我们分析的亲本贡献。估计了基因和单倍型多样性,结果显示南美印第安人样本的这些参数值比巴西人小。为了更全面地了解整个巴西人群的遗传结构,将来自RS样本的Y-STR数据与已发表的数据进行了比较。在进行的比较中未观察到遗传亚结构。多维尺度分析证实了大多数巴西Y染色体父系谱系的欧洲来源。
