Figure 6From: The dynamics of alternative pathways to compensatory substitutionReversions to the ancestral state. The average number of times returning to state AB after having been fixed for a deleterious intermediate state are shown under four mutation rates (panels) across a variety of selection coefficients. The analytical predictions (lines) from β of the number of recursions match well with results from simulations without recombination (points), except when the mutation rate is very large.Back to article page
