Potential targets of Bab regulation in the UVI scale type.
A. Box and whiskers plot of probability of differential expression, binned by number of called Bab ChIP sites in proximity to each gene (Wilcoxon rank sum tests; *: p < 0.01; ***: p < 1e−15). B. Expression dot plot visualization of selected UVI-DE genes (log2FC > 1.8, adjusted p < 0.01) with at least 3 Bab ChIP peaks and potential roles in ultrastructural specialization (Data 5 at https://osf.io/yjvkc/). C, D. Volcano plots of UVI-DE genes (Data 7-8 at https://osf.io/yjvkc/), colored by number of Bab ChIP sites (C), and by the presence of selective sweeps in a sympatric population of C. eurytheme x C. philodice (D). These two morphospecies hybridize and show genome-wide admixture across autosomes (dendrograms reproduced from [29], resulting in a population polymorphic for UV iridescence (present in C. eurytheme, absent in C. philodice).
