From: Tetrapod V1R-like ora genes in an early-diverging ray-finned fish species: the canonical six ora gene repertoire of teleost fish resulted from gene loss in a larger ancestral repertoire

Fig. 5

Evolutionary dynamics of ora genes. A taxonomy tree of cartilaginous, lobe-finned and ray-finned fish is shown. Species are indicated by the initials of their Latin names, see TableĀ 1 for full names. Arrows indicate the minimal evolutionary age of genes as predicted by parsimony. Red cross, gene loss, red numbers indicate the gene lost; blue circle, gene duplication, blue numbers indicate the gene duplicated; grey rectangle, intron gain; only events in the ray-finned lineage are shown. The relative order of symbols within one segment is arbitrary. Note that ancestral genes ORA7-8 are lost early in the teleost lineage
