Phylogenetic tree for the 18 vertebrate aromatase genes. Numbers above the branches represent the KA/Ks ratios, while numbers below indicate branches highlighted in Figure 6. Single and double asterisks represent bootstrap values of 95–99% and 100%, respectively. The following sequences were used: Tilapia nilotica (rainbow trout), gi:1613859, Oryzias latipes (medaka), gi:1786171, Danio rerio (zebrafish), gi:2306966, Carassius auratus (goldfish, ovary), gi:2662330, Ictalurus punctatus (catfish), gi:912802, Carassius auratus (goldfish, brain), gi:2662328, Sus scrofa (pig) placental, isoform 2, gi:1762232, Sus scrofa (pig) embryo, isoform 3, gi:1244543, Sus scrofa (pig) ovary, isoform 1, gi:1928957, Bos taurus (ox), gi:665546, Equus caballus (horse), gi:2921277, Mus musculus (mouse), gi:3046857, Rattus norvegicus (rat), gi:203804, Oryctolagus cuniculus (rabbit), gi:2493381, Homo sapiens (human), gi:28846, Gallus gallus (chicken), gi:211703, Poephila guttata (zebra finch, ovary), gi:926845, Ovis aries (sheep), gi:7673985.
