The National Institute of Fisheries Science in South Korea has created the world's best standard genome map of flatfish, which distinctly separates the genetic information of male and female fish. This achievement, made in collaboration with Chungnam National University, has been registered with the National Center for Biotechnology Information and published in Scientific Data. The institute used the latest genome sequence analysis technology to create a standard genome map for both female and male Korean flatfish, surpassing the quality of the Chinese standard genome. This genome map will be used to improve flatfish breeds by discovering genetic mutations linked to desirable traits.
