The oral versus pharyngeal jaws expression differences of seven target genes in haplochromine cichlids from three East African lakes at the end of larval phase. (A) Comparisons of relative expression levels between oral and pharyngeal jaws for seven candidate target genes in different lakes in East Africa at the yolk sac absorption stage marking the end of larval development and the onset of juvenile phase. Circles above bars indicate significantly elevated expression (P < 0.05) in comparisons between oral and pharyngeal jaws (i.e., compared to the bar matching the colour code of the circle); the comparisons were restricted within the species
