Figure 1. Correlations of mRNA levels for human, chimpanzee, and rhesus macaque orthologous genes.

Figure 1

Spearman correlation heatmaps and hierarchical clustering for (a) all orthologous genes, (b) all transcription factors orthologous genes (except ZFs), and (c) KRAB-ZF only. The highest Spearman correlation coefficients correspond to brown colors. (a) Expression of all orthologous genes and (b) expression of all human transcription factors cluster according to tissue, with a high Spearman correlation coefficient. (c) Expression of KRAB-ZF genes clusters according to species, with a high Spearman correlation coefficient.
