Movant strain fitness in pairwise competition experiments. S10 relocation effect on fitness was assessed by averaging the obtained W values against Parental−1120::gfpmut3* of the parental, movant, and merodiploid strains. Results are shown in standard box-and-whisker plots showing the medians, minima, and maxima of W values. Statistical significance was analyzed using nonparametric tests and the Dunn test for multiple comparisons of the means obtained for each strain. (a) Competition experiments done under fast-growth conditions when overlapping replication rounds occur as depicted in the right panel. Letters denote groups showing statistically significant differences (P of at least <0.01). (b) Competition experiments performed under slow-growth conditions in the absence of multifork replication as depicted in the right panel. ****, P < 0.0001. The rest display no statistically significant differences with respect to the parental strain.
