Abstract

Haplotypes and allele frequencies for 12 Y-STR loci were determined in Sichuan Han ethnic population samples of 237 unrelated males living in west China. Only one haplotype was encountered in triple. Twelve of the haplotypes were encountered in duplicate, while 210 haplotypes were unique. The gene diversity was 0.9952. This study provides an essential precondition for identification of male DNA and tracing of paternal lineages.

摘要

在居住于中国西部的237名无血缘关系的四川汉族男性群体样本中，测定了12个Y染色体短串联重复序列（Y-STR）基因座的单倍型和等位基因频率。仅发现1个单倍型出现了3次。12个单倍型出现了2次，而210个单倍型是独特的。基因多样性为0.9952。本研究为男性DNA鉴定和父系谱系追踪提供了重要前提条件。
