Abstract

Competition experiments between Escherichia coli mutL and mut^+^ populations show that the mutator gene confers a selective advantage on the strain which carries it. Fitness values vary from experiment to experiment.

Previous studies have shown that the mutT, mutH and mutL mutators of Escherichia coli have a marked advantage in competition growth with otherwise coisogenic wild-type strains. As shown in this paper the same is true for the mutS mismatch mutator. In three experiments mutS could outgrow the wild-typ
