Figure 4From: Transcriptome analysis reveals novel patterning and pigmentation genes underlying Heliconius butterfly wing pattern variationMean gene expression of optix by wing section. Bars are colored by the distinguishing color of the wing section. Asterisks indicate stages with significant differential expression by color. Y-axis gene expression is log2 microarray intensities. hyb: hybrid form; pet: petiverana; a: amphitrite; e: emma; f: favorinus; FW: forewing; HW: hindwing.Back to article page
