Statistical justification of threshold values - 100, 100, and 170 for topologies KO, KC, and KS, respectively - used to identify recombination events. Values on the x-axis are maximal local scores. EVD probability densities for the maximum maximal local score attained by random walks of length M' appear as bell-shaped curves with a pronounced skew to the right. Threshold values, demarcated by vertical lines, correspond to conservative significance levels (α = 0.05) for these distributions.
