Venn diagrams show the numbers of shared and unshared FOXP2 putative promoter regions of genes among different experimental conditions. A Adult conditions: Adult males vs adult females. B Male conditions: Adult males vs juvenile non-singing males vs. juvenile singing males. C Female conditions: Adult females vs. juvenile females. D Juvenile conditions: Juvenile non-singing males vs. juvenile singing males vs. juvenile females NS Non-singing, S singing. All adult males are non-singing. All gene counts exclude putative promoter peaks within tRNAs
