Genetic structure of a population can be influenced by evolutionary processes and cultural histories which can alter the frequencies of different variants at particular genetic markers. These characteristics make DNA evidence suitable for forensic applications. Little relevant data are available from the interior Sindhi population; thus, in the current study, we have investigated 15 autosomal STRs in 181 unrelated individuals belonging to the interior parts of Sindh Pakistan, to establish its lineage and parameters of forensic interest. These STRs revealed a high power of discrimination (CPD), power of exclusion (CPE) and matching probability (CMP) are 0.9999999999999999968997, 0.99998612 and 3.1003 × 10–18 respectively. The genetic distances, neighbour‐joining (NJ) tree, interactivity test and principal component analysis (PCA) based on 15 autosomal STR loci showed that the interior Sindhi population had a closer genetic relationship with Pakistani populations and distant relationships with regional (India and Afghanistan) populations. The present findings exhibited that STRs included in AmpFLSTR Identifiler kit (Applied Biosystems) are genetically polymorphic in the interior Sindhi population of Pakistan. This study provides valuable population genetic data for the genetic information study, forensic human individual identification and paternity testing.

巴基斯坦内部信德族群中 15 种常染色体 STR 的遗传特征及其与其他族群的系统发育关系

种群的遗传结构会受到进化过程和文化历史的影响,这会改变特定遗传标记处不同变异的频率。这些特征使 DNA 证据适用于法医应用。内陆信德人口的相关数据很少;因此,在目前的研究中,我们调查了属于巴基斯坦信德省内陆地区的 181 个无关个体的 15 个常染色体 STR,以确定其谱系和法医兴趣参数。这些 STR 显示出高分辨力 (CPD)、排除力 (CPE) 和匹配概率 (CMP) 分别为 0.9999999999999999968997、0.99998612 和 3.1003 × 10–18。遗传距离,邻接(NJ)树,基于 15 个常染色体 STR 基因座的交互性检验和主成分分析 (PCA) 表明,内部信德种群与巴基斯坦种群的亲缘关系较近,与区域(印度和阿富汗)种群的亲缘关系较远。目前的研究结果表明,包含在 AmpFLSTR Identifiler 试剂盒(Applied Biosystems)中的 STR 在巴基斯坦内部信德人口中具有遗传多态性。本研究为遗传信息研究、法医人类个体鉴定和亲子鉴定提供了宝贵的群体遗传数据。目前的研究结果表明,包含在 AmpFLSTR Identifiler 试剂盒(Applied Biosystems)中的 STR 在巴基斯坦内部信德人口中具有遗传多态性。本研究为遗传信息研究、法医人类个体鉴定和亲子鉴定提供了宝贵的群体遗传数据。目前的研究结果表明,包含在 AmpFLSTR Identifiler 试剂盒(Applied Biosystems)中的 STR 在巴基斯坦内部信德人口中具有遗传多态性。本研究为遗传信息研究、法医人类个体鉴定和亲子鉴定提供了宝贵的群体遗传数据。
