  • *P values (CI of mutant significantly different from CI of wild type by Mann–Whitney nonparametric test) were <0.0001 for all competitions.

  • Dev. is the absolute average deviation from the median (see Materials and Methods). Note: the CI was positive for all competitions.

  • N is the number of independent colony competitions for each mutant.
