Figure 4From: Evolution and origin of vomeronasal-type odorant receptor gene repertoire in fishesChromosomal locations of V2R genes in zebrafish, medaka, pufferfish, and fugu. Each subfamily is indicated in color as in Figure 3. Asterisks indicate pseudogenes. Note that the scale of the V2R cluster is different among species. The length of the V2R cluster region in each species is shown in parentheses. In fugu, only four representative scaffolds that contain V2R genes are shown.Back to article page
