Fig. 4From: Adapting the engine to the fuel: mutator populations can reduce the mutational load by reorganizing their genome structureDistribution of the effect of duplications on metabolic error in the ancestral lineages of all the mutator populations. Duplications are deleterious when they increase metabolic error (i.e., variations are positive). The large red bar of error rate increasing events at the right edge shows the prevalence of deleterious duplications with effects equal to or larger than 0.01Back to article page
