Relative expression levels (log₂ CPM) across all samples of 196 differentially expressed genes between sympatric and allopatric females (A), and 78 differentially expressed genes between sympatric and allopatric males (B). The dendrograms resulted from hierarchical clustering of expression levels after 100 replicates to estimate Approximately Unbiased p-values (numbers on nodes). Note that the differences between dendrograms require that the individuals and groups be presented in different order at the bottom of the heatmaps
