Correlations of single-copy genes and gene family members. We show scatter plots comparing tissue-specific correlations of single-copy genes and gene family members on the species pairs: (a) chicken versus human, (b) chicken versus opossum, (c) opossum versus chimpanzee, (d) opossum versus human, (e) human versus chimpanzee, and (f) human versus gorilla. In all panels, Spearman’s correlation is shown on the x-axis for single-copy genes, and on the y-axis for gene families. Tissue comparisons are coded by color (see legend), in all cases, brain tissues (labeled as ‘brain’ and ‘cerebellum’ are more correlated for gene families (black dots), while mismatched-tissue comparisons, with the exception of the brain and cerebellum tissues, are more correlated for single copy genes (light grey dots).
