Abstract: With the universal use of molecular identification, species evolution analysis and whole-genome breeding, accurate genomic-wide SNP genotyping has become the key to genome research in livestock and poultry. Genotyping array, whole genome resequencing (WGS), reduced-representation genome sequencing (RRGS) and target capture sequencing have been widely used in livestock and poultry genomic research. In this paper, the principle of genomic-wide SNP genotyping technology and its application in genome-wide association studies, selection signal analysis and background analysis of livestock and poultry genetic resources were summarized, in order to provide reference for livestock and poultry genome research and genetic breeding.
