Figure 1.
Consensus phylogenetic relationships between fish (simplified from Nelson 1994; Inoue et al. 2003) and tetraopods, including fish considered as biological models (underlined), and those for which a sequence has been published (boxed, continous line) or is underway (boxed, dashed line). The thick branch indicates the most likely position of the whole-genome duplication at the root of the teleosts, based on Hoegg et al. (2004).
