Log-fold expression (transcripts per million) levels of putatively melanin related genes that are differentially expressed between color morphs in Dendrobates auratus. Each individual is represented on the x-axis, and the y-axis represents expression levels for each transcript that annotated to an melanophore-related gene. Genes represented more than once mapped to multiple transcripts. Expression for this heatmap was calculated using transcripts per million in Kallisto, to which we added 1 and log transformed the data (i.e., expression = log(transcripts per million + 1).
