Figure 3From: Further statistical analysis for genome-wide expression evolution in primate brain/liver/fibroblast tissueHistogram of the ratio between induced/repressed gene expression (l/R) in the human and chimpanzee lineage in brain, liver and fibroblast tissue. (a) Using a standard two-sample t-test for the differential gene expressions. (b) Using the regularised t-test (Cyber-T) for the differential gene expressions.Back to article page
