A neighbor-joining tree based on the partial mitochondrial DNA COI gene region using Sebastes koreanus (KIOST_22_001) showing the relations among the four species of Sebastes and one outgroup (Sebastiscus marmoratus). Numbers at the branches indicate bootstrap probabilities in 10 000 bootstrap replications. Scale bar equals 0.01 of Tamura and Nei’s distance (1993) with K2 parameter model. Abbreviation: COI, cytochrome oxidase subunit I.
