Signature of selection in livestock is a method used to identify genomic regions and candidate genes related to economic traits when phenotypic information is unknown. This study used 406 beef cattle (203 Hanwoo and 203 Angus) with a whole-genome sequence to find selection signatures. As a result, we identified 298 significant genomic regions within Hanwoo, including the candidate genes such as LPL related to the lipid metabolism and 33 genomic regions within Angus with HK1 and ACTC1 genes linked with glucose metabolism and muscle formation. From the between populations results, 36 significant genomic regions were detected, including the CCKBR gene associated with the feed efficiency. This study can assist in understanding the history of these breeds and identifying the genomic regions under selection for breeding programs in beef cattle.
