Relatedness, habitats, trophic specialization and expression levels of candidate reference genes in the jaws of haplochromine cichlid species used in this study. a A simplified phylogenetic tree of the East African haplochromine cichlids displaying the relatedness between the species specified by their habitats/lakes and trophic specializations. The symbol colour for each species represents related trophic niche whereas the symbol shape refers to its habitat/lake. b Expression levels of candidate reference genes based on raw Cq values in oral or pharyngeal jaws across all of the species. In each box plot, the middle line represents the median and boxes lower and upper limits indicate the 25/75 percentiles
