Genome wide distribution of cone opsin QTL. Quantitative trait loci (QTL) mapping detected 12 intervals on 5 LGs that segregated for the differential expression of cone opsins between the two F0 species. In the single cones, SWS1 and SWS2B have 3 co-localizing QTLs on LG14, LG17 and LG20. While RH2B in the double cones has only 1 QTL on LG16, RH2A and LWS share 2 QTL on LG10 and LG16. Single cones and double cones share 1 QTL on LG14. Each cone opsin QTL is indicated by a separate color depicted in the color legend. The cone opsins in cichlids are present on two chromosomes- LG5 (SWS2B, SWS2A, LWS, RH2B, RH2Aα, RH2Aβ) and LG17 (SWS1). The black lines represent RAD loci
