Figure 2.
Relative frequency over time (generation) of the superior competitor during the competition experiment. Filled symbols represent the clone evolved on the structured plate of our long-term experiment; open symbols represent the clone evolved on the mixed plate. No significant fitness difference is found between the clones. The different treatments represent the different degrees of mixing. The difference in density of the various starting ‘spots’ of the superior competitor is negligible (the density on the plate is everywhere about 8.9×105 cm−2) and does not influence the competition.
