Fig. 1From: Gene losses, parallel evolution and heightened expression confer adaptations to dedicated cleaning behaviourGene family size change and dN/dS ratios of Labridae fish species. A Phylogeny of fourteen fish species including eight Labridae fish species and six reference fish species in this study. Bold numbers indicated the significant expanded and contracted gene families compared to the node of the most recent common ancestor. B The dN/dS ratios of eight Labridae and six reference fish species based on 6929 sub-orthogroup genes. Y axis indicates the dN/dS ratios of genes per species. The dash line means the median dN/dS of L. dimidiatusBack to article page
