Allele frequencies and haplotypes of 11 Y-chromosome STR loci, DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385 ab, DYS438, DYS439 and DYS437 were determined in 320 unrelated Yunnan Han Chinese males. A total of 293 haplotypes were identified, of which 268 were unique, 23 were shared in two individuals, and 2 were shared in three individuals. The allele diversity values for each locus ranged from 0.4087 (DYS438) to 0.9701 (DYS385). The allele observed haplotypes diversity value was 0.9994. The combined Y-chromosome STR polymorphisms provide a powerful discrimination tool for routine forensic applications.
在 320 名无血缘关系的云南汉族男性中,确定了 11 个 Y 染色体 STR 基因座(DYS19、DYS389I、DYS389II、DYS390、DYS391、DYS392、DYS393、DYS385ab、DYS438、DYS439 和 DYS437)的等位基因频率和单倍型。共鉴定出 293 种单倍型,其中 268 种为独特单倍型,23 种在 2 个人中共享,2 种在 3 个人中共享。每个基因座的等位基因多样性值范围为 0.4087(DYS438)至 0.9701(DYS385)。观察到的等位基因单倍型多样性值为 0.9994。联合 Y 染色体 STR 多态性为常规法医应用提供了强大的鉴别工具。
