Fig. 2.— — Neighbor-joining tree for OlfC genes of seven teleost fishes. The OlfC genes of zebrafish (Danio rerio [Dr]), Atlantic salmon (Salmo salar [Ss]), three-spined stickleback (Gasterosteus aculeatus [Ga]), fugu (Takihfugu rubripes [Tr]), green-spotted pufferfish (Tetraodon nigroviridis [Tn]), medaka (Oryzias latipes [Ol]), and Lake Victoria cichlid (Haplochromis chilotes [Hc]) are indicated by different colors. Triangles indicate the lineage-specific gene expansions. The vertical height of these triangles is proportional to the number of genes. All the nodes with bootstrap values higher than 85 in the neighbor-joining (NJ) tree were also supported by maximum likelihood (ML) tree.
