[i] R indicates the correlation coefficient of gene expression between human and mouse, measured over 16 tissues. The percentages indicate the ratios between the fraction of genes having an R-value above the specified level in the set of orthologs where a species-specific duplication is present (163 sets for human and 139 for mouse) compared with the fraction in the set of 1325 orthologs where there have been no species-specific duplications. p-values were calculated from 10,000 Monte Carlo randomizations.
