  1. Pearson correlation coefficient (r) was used to assess the similarity between expression pattern of the target genes between oral and pharyngeal jaws across the haplochromine species in each lake or trophic niche specialization. NS indicates no significant expression correlation between the two jaw types in a given comparison
