Extended Data Fig. 6: Comparisons of similarity index values (Pearson coefficients) between expression profiles (in log2(TPM+1)) of orthologous genes between dioicous and monoicous species within species pairs (PSO), per category of gene.

Similarity index are represented separately for mean female (red) and mean male (blue) expression profiles and for three categories of orthologous genes: male-biased genes in the dioicous species (MBG), female-biased genes in the dioicous species (FBG) and unbiased genes (UnB). Asterisks represent significant differences between Pearson coefficients, taking into account the correlations between compared gene sets, tested using a two-sided significance test with the cocor package in R.
