The numbers of TFs and TFBSs for de novo genes, duplicated new genes, and orthologous genes. Comparison of the average number of TFs regulating a gene (A), and the average number of TFBSs in a gene (B) for de novo genes, duplicated new genes, and orthologous genes. No significant differences were observed (two-sided Wilcoxon test).
