太原漢族人群17個(gè)Y-STR基因座等位基因頻率及遺傳關(guān)系
[Abstract]:Objective to study the frequency, genetic polymorphism, genetic distance and cluster analysis of 17 Y-STR alleles in Taiyuan Han population and their application in forensic medicine. Methods the blood samples of 102 unrelated men of Taiyuan Han nationality were detected by Y-filerTM kit. The allele frequency was calculated by 3130 xl genetic analyzer. The genetic distance and genetic relationship of Taiyuan Han population were studied by using correlation analysis software and referring to other population data. Results there were 137 alleles in 17 Y-STR loci. The genetic diversity ranged from 0.433 to 0.894 0. According to genetic distance analysis, the genetic distance between Taiyuan Han and Beijing Han was the smallest (0.001 7), compared with the published data of other populations in China. The distance between Taiya and Taiwan is the largest (0.469 6); Compared with other minorities, the genetic distance between Taiyuan Han and Liaoning Manchu population was the smallest (0.001 4), and the distance between Taiyuan Han and Taiwanese Atayal population was the largest (0.4696). Conclusion 17 Y-STR loci have good genetic polymorphisms in Taiyuan Han population, and have strong ability of individual recognition and non-paternal exclusion, which is of great significance for the establishment of Y chromosome database and forensic medical practice.
