Figure 3From: Analysis of transitions at two-fold redundant sites in mammalian genomes. Transition redundant approach-to-equilibrium (TREx) distance metricsHistogram showing the f2Y (a) and f2R (b) values of all mouse:rat intertaxa homolog pairs containing 50 or more characters. The peak centered at ca. 0.88 (a) and ca. 0.90 (b) reflect true orthologs. Pairs with f2 values near 0.53 diverged so long ago that the silent sites have equilibrated.Back to article page
