Figure 3 From: Evolution favors protein mutational robustness in sufficiently large populations Accumulation of nucleotide (〈 m nt 〉) and nonsynonymous (〈 m aa 〉) mutations in the experimentally evolved P450 populations. For the unselected and monomorphic populations, numbers are the average over all replicates at the indicated generation; for the polymorphic population they are from a random sample, with sampling standard error shown.Back to article page
