Fig. 4From: The relationship between regulatory changes in cis and trans and the evolution of gene expression in humans and chimpanzeesGenes with high cis proportion show evidence of relaxation of constraint. Boxplot showing the distribution of A percent coding identity B dN/dS or C LOEUF for genes with a high, moderate, or low cis proportion. Boxplots showing diploid expression relative to mean human expression in select cell types for D CLDN4 or E CEPBA. Adjacent heatmaps show the median diploid expression across all samples from both speciesBack to article page
