New csgA mutants have relative fitness similar to their parent in mixed groups but are generally outcompeted by non-parental cooperators. Sporulation fitness (Wij) of csgA mutants relative to developmentally proficient partners in initially 1:99 (mutant:partner) mixed groups. Small transparent circles represent individual replicate estimates, large solid circles show cross-replicate averages, and error bars show 95% confidence intervals; 4 biological replicates
