Colonization efficiency and relative competitive fitness of the parental line and the five evolved lines with changed fitness.

a) Bars indicate relative competitive ability in colonization of mycelium G1 (mycelium used as female during evolution) after 1 and 5 cm migration, as indicated in the figure above each graph (first two bars) and relative competitive fitness (light bar). b) as a) but with receiving mycelium G2 used. Measurements of 9 replicates. Error bars are standard error.
