The tree is mid-point rooted. Numbers at the branches denote bootstrap values (maximum likelihood/neighbor joining). Bootstrap values above 50 are shown. Tyrp1a and Tyrp1b are assigned according to the analysis of their genomic environment. (b) Synteny of -containing regions in vertebrate genomes. The human region is syntenic to two paralogons in Tetraodon (Tni), stickleback (Gac) and medaka (Ola). was apparently lost in the zebrafish (Dre). (c) Synteny of -containing regions in vertebrate genomes. The human region is syntenic to two paralogons in stickleback, medaka and zebrafish. A pseudogene is found in Tetraodon (asterisk). Numbered bars represent genes contributing to conserved synteny, genes that do not contribute to conserved synteny are not shown. Blue bars indicate genes that are duplicated along with or , respectively. Dotted lines connect orthologous genes. (grey bars), another teleost-specific pigmentation gene duplicate [17] is found 3' of in the four teleost genomes but belongs to a different paralogon (see text)
