Fig. 3. Median of ratio of nonsynonymous to synonymous diversity Πn/Πs compared between different data sets. Increase in strength of purifying selection from UED-repressed to tissuewise subfunctionalized (BED) to UED-dominant genes. P values were calculated using Wilcoxon rank-sum test: ****P < 2.2 × 10<sup>−16</sup>; ***P = 1.9 × 10<sup>−15</sup>; **P = 2 × 10<sup>−6</sup>; *P = 3 × 10<sup>−4</sup>.

Fig. 4. Ratio of nonsynonymous to synonymous nucleotide diversity (Πn/Πs) for maize subgenome 1 and 2 genes for different expression classifications. UED-D, UED-dominant; UED-R, UED-repressed. P values were calculated using Wilcoxon rank-sum test: *P = 2.9 × 10<sup>−4</sup>; ns, not significant.
