Figure S1 Dependence of the variances Vip(i) and Vg(i) on the noise strength. Figure S2 Correlation between gene expressions. Figure S3 Correlation between errors by noise and mutation over all genes. Figure S4 Relationship between V (i) and Vip(i) for evolved GRNs with a larger fraction of target genes, and a smaller fraction of nonzero genes. Figure S5 Relationship between Vg(i) and Vip(i) for the gene expression dynamics whose noise level depends on each gene. Figure S6 Relationship between Vg(i) and Vip(i) for a model with "extrinsic noise."
