在巴西，历史上孤立的人口之间的混合程度是复杂的，在地理上是可变的。关于这种混合的遗传和表型后果的研究存在分歧。在巴西东北部，我们招募了522名萨尔瓦多居民和620名福塔莱萨居民，他们自我宣布的肤色分布与全国人口普查结果相当。使用结构和主成分分析程序，生物地理血统与肤色类别之间存在明显的相关性。这种与非洲血统的相关性在萨尔瓦多更强(r=0.585； P
The degree of admixture in Brazil between historically isolated populations is complex and geographically variable. Studies differ as to what the genetic and phenotypic consequences of this mixing have been. In Northeastern Brazil, we enrolled 522 residents of Salvador and 620 of Fortaleza whose distributions of self-declared color were comparable to those in the national census. Using the program Structure and principal components analysis there was a clear correlation between biogeographic ancestry and categories of skin color. This correlation with African ancestry was stronger in Salvador (r=0.585; P
