Amount of DNA a), coding size b), noncoding size c) and coding fraction d) for the different combinations of μ and N tested, after 2 million generations. For each of the 5 WTs, 10 replicas were performed for each tested set of conditions. Control conditions (⁠$N=1,024$ and $μ=1.10−6$⁠) are outlined in black. For the combination of both the highest mutation rate and the largest population size, only the median was tested due to computational limitations, which is indicated by a (*).
