In this study, we intend to identify the evolutionary footprints of the South Iberian population focusing on the Berber and Arab influence, which has received little attention in the literature. Analysis of the Y-chromosome variation represents a convenient way to assess the genetic contribution of North African populations to the present-day South Iberian genetic pool and could help to reconstruct other demographic events that could have influenced on that region. A total of 26 Y-SNPs and 17 Y-STRs were genotyped in 144 samples from 26 different districts of South Iberia in order to assess the male genetic composition and the level of substructure of male lineages in this area. To obtain a more comprehensive picture of the genetic structure of the South Iberian region as a whole, our data were compared with published data on neighboring populations. Our analyses allow us to confirm the specific impact of the Arab and Berber expansion and dominion of the Peninsula. Nevertheless, our results suggest that this influence is not bigger in Andalusia than in other Iberian populations.
在本研究中，我们旨在聚焦柏柏尔人和阿拉伯人的影响来识别南伊比利亚人群的进化足迹，而这在文献中很少受到关注。对Y染色体变异的分析是评估北非人群对当今南伊比利亚基因库的遗传贡献的便捷方式，并且有助于重建其他可能影响该地区的人口事件。对来自南伊比利亚26个不同地区的144个样本进行了总共26个Y-SNP和17个Y-STR的基因分型，以评估该地区男性的遗传组成和男性谱系的亚结构水平。为了更全面地了解整个南伊比利亚地区的遗传结构，我们将我们的数据与邻近人群的已发表数据进行了比较。我们的分析使我们能够确认阿拉伯人和柏柏尔人扩张以及对半岛统治的具体影响。然而，我们的结果表明，这种影响在安达卢西亚并不比在其他伊比利亚人群中更大。
