摘要: Y染色体是男性所特有的父系遗传染色体,Y染色体上的STR基因座已经大量应用于实际案件。本文总结了Y-STR的特性以及选择适合中国人群的Y-STR基因座所需要考虑的问题,展望了Y-STR在家系排查、亲缘搜索、来源人群推断、混合样本检验、亲缘关系鉴定等方面的应用前景,并探讨了Y-STR试剂盒研发、验证,Y-STR突变率,搜索软件等方面的问题,提出了相应的建议。

Abstract: Y chromosome is a male-specific paternal inherited chromosome. The STR markers on Y chromosome have been widely used in forensic practices. This article summarizes the characteristics of Y-STR and some factors are considered of selecting appropriate Y-STR markers for Chinese population. The prospects of existing and potential forensic applications of Y-STR profiles are discussed including familial excluding, familial searching, crowd source deducing, mixture sample testing, and kinship identifying. The research, development, verification of Y-STR kit, Y-STR mutation rate, and search software are explored and some suggestions are given.
