FIG. 6.

Noncompetent lineages of A. baylyi overtake competent lineages more rapidly than predicted in direct competition. The rate at which the noncompetent lineages overtake the population is higher than predicted by two equations: (i) using equation 2, which was used to determine selection coefficients in the initial competitions, assuming that s = 0.012 generation⁻¹ (see Materials and Methods) (29), and (ii) using equation 4 (see Materials and Methods) (13). Shown are the means and standard deviations for five competitions, as well as predicted values based on the two equations discussed.
