摘　　要：人工选择对家鸡驯化及品种形成具有重要作用,基因组上留有选择痕迹。随着基因组技术和选择信号检测方法完善,在基因组上检测选择信号成为进化生物学领域研究热点。文章主要描述选择信号定义,总结检测选择信号的重要统计方法,分析鸡基因组选择信号检测结果,以期为鸡全基因组领域研究提供参考。Artificial selection played an important role during chicken domestication and subsequent breed formation. So the imprints of selection episodes had been left within chicken genome. With the advances in genomics and the development of methods to detect selection signatures, the elucidation of these selection signatures had been of interest issue on the fields of evolutionary biology and population genetics. The aims of this review were to describe the definition of selection signatures on chicken genome, to present the main statistical methods used to detect selection signature, and to summarize some recent results on the selection footprint in chicken. This review should offer references to the researchers in the related fields.
