Phylogenetic relationships  of fish species indicating the five (*) whose genomes have been sequenced and which are in the public domain  (fugu, Takifugu rubripes; tetraodon, Tetraodon nigroviridis; medaka, Oryzias latipes; stickleback, Gasterosteus aculeatus; and zebrafish, Danio rerio), as well as the species (†) that are currently being sequenced. The red vertical arrows indicate where whole genome duplications have occurred. The Gar, a representative of an ancient group of bony fish that did not undergo the whole genome duplication at the base of the tree, is an outgroup to the other species.
