Figure 4From: Analysis of transitions at two-fold redundant sites in mammalian genomes. Transition redundant approach-to-equilibrium (TREx) distance metricsHistogram showing the frequency of n, the number of characters used to calculate the f2Y (a) and f2R (b) values, in the mouse:rat intertaxa orthologs. The mean (λ) of the Poisson distribution for f2Y is 136.6 (95% ci 130.1.7–141.2) while the one for f2R 138.2 (95% ci 134.3–140.5). ci: confidence interval. The bin size is 25 sites.Back to article page
