The Bahamian archipelago has been influenced by a wide array of settlers (Lucayans, Eleutherian Adventurers, British Loyalists, Creoles from the United States and African slaves) throughout its short but dynamic history. Nevertheless, the Bahamas remains poorly characterized genetically and little is known about each group's contribution to the island chain. In the current study, the population of New Providence was analyzed based on 15 autosomal STR loci routinely employed in forensic DNA fingerprinting applications. A comparison of this collection with African groups reveals similar genetic profiles to West African populations from Equatorial Guinea and Angola, possibly resulting from the importation of slaves from West African ports during the Transatlantic Slave Trade. Although the New Providence collection exhibits strong genetic affinities to the two US African American reference populations, the detection of unique alleles among them may necessitate the utilization of population-specific databases in forensic cases especially when the STR profiles include these specific variants.
在其短暂而充满活力的历史中，巴哈马群岛受到了众多定居者（卢卡扬人、伊柳塞拉冒险家、英国效忠派、来自美国的克里奥尔人以及非洲奴隶）的影响。然而，巴哈马群岛在基因方面的特征仍然鲜为人知，对于每个群体对该岛链的贡献也知之甚少。在当前的研究中，基于法医DNA指纹识别应用中常规使用的15个常染色体STR位点，对新普罗维登斯的人口进行了分析。将该样本集与非洲群体进行比较后发现，其基因图谱与赤道几内亚和安哥拉的西非人群相似，这可能是由于跨大西洋奴隶贸易期间从西非港口进口奴隶所致。尽管新普罗维登斯的样本集与两个美国非裔美国人参考群体表现出很强的基因亲和力，但在其中检测到的独特等位基因可能需要在法医案件中使用特定人群的数据库，尤其是当STR图谱包含这些特定变体时。
