Abstract: Whole-genome sequencing mainly refers to obtain the full genome sequence map of a species through different sequencing and assembly alignment method,and based on it to explore their genetic diversity,selection signal,and the origin and evolution of representative individuals or groups by constructing whole-genome genetic variation map. Using single nucleotide polymorphism(SNP),insertion and deletion(Indel)and copy number variation(CNV)genetic variation as molecular markers,the studies on whole-genome sequencing has been achieved a lot in the origin and evolution of domestic animal,domestication,adaptive mechanism,candidate genes for important economic traits,and population demographic. This paper focuses on the key achievements of whole-genome sequencing on common domesticated animals(such as pig,horse,cattle,sheep,goat,and closely-related species),and discusses the advantages,disadvantages and significance of whole-genome sequencing in production. In addition,this paper summarizes and prospects the future development of researches on whole-genome sequencing. And we also hope to provide a reference for mapping functional genes with important economic traits and the origin domestication of domesticated animals.

Key words: whole-genome sequencing, genetic variation, functional gene, single-nucleotide polymorphism
