Bar Plot from Scientific Research

Total number of OLF genes in 201 ray-finned fish species, coloured by gene family (Additional file 2 : Table S1). Median value is indicated (M.). Right, number of OR, TAAR, V1R and V2R receptors found in different genomic clusters for those species with the higher number of genes within each of the taxonomic orders presenting more than 500 OLF genes (Additional file 2 : Table S2). Loci containing less than five receptor genes are excluded for visualization purposes.
