The West Indies represent an amalgamation of African, European and in some cases, East Asian sources, but the contributions from each ethnic group remain relatively unexplored from a genetic perspective. In the present study, we report, for the first time, allelic frequency data across the complete set of 15 autosomal STR loci for general collections from Haiti and Jamaica, which were subsequently used to examine the genetic diversity present in each island population. Our results indicate that although both Haiti and Jamaica display genetic affinities with the continental African collections, a stronger African signal is detected in Haiti than in Jamaica. Although only minimal contributions from non-African sources were observed in Haiti, Jamaica displays genetic input from both European and East Asian sources, an admixture profile similar to other New World collections of African descent analyzed in this report. The divergent genetic signatures present in these populations allude to the different migratory events of Africans, Europeans, and East Asians into the New World.
西印度群岛是非洲、欧洲和在某些情况下东亚各种族的融合体，但从遗传学角度来看，每个族群的贡献仍然相对没有得到充分探索。在本研究中，我们首次报告了来自海地和牙买加的一般群体的 15 个常染色体 STR 基因座的全部等位基因频率数据，随后用于研究每个岛屿群体的遗传多样性。我们的结果表明，尽管海地和牙买加与非洲大陆的群体都具有遗传相似性，但在海地检测到的非洲信号更强。尽管在海地只观察到来自非非洲来源的最小贡献，但牙买加显示出来自欧洲和东亚来源的遗传输入，这与本报告分析的其他具有非洲血统的新世界群体的混合模式相似。这些群体中存在的不同遗传特征暗示了非洲人、欧洲人和东亚人进入新世界的不同迁徙事件。
