Supplementary Figure S2: Gene expression directionality outside and within the supergene region. Stacked bar plots showing the directional pattern of differential expression of genes outside and within the supergene. Numbers indicate the number of differentially expressed genes (FDR < 0.01) in a given category. “Multifactorial” indicates that the DEG’s were inferred using the Multifactorial-model method. “Brain” and “Ovary” indicate that the DEGs were inferred using tissue-specific pairwise comparisons of polygyne individuals. * P < 0.05, ** P < 0.01, X2-test.
