Synteny analyses of visual opsin genes between turbot and five other teleost species (tongue sole, medaka, zebra mbuna, zebrafish, and guppy). a SWS1, b RH2, c LWS and SWS2, d RH1. Different gene families are represented by colored pentagons, and the direction of the pentagon indicates gene orientation. The dashed lines indicate that two adjacent genes in that species are not directly linked
