Genetic drift and selection in many-allele range expansions
Fig 13
Left: Single sectors of our eYFP, eCFP, and black strains sweeping through the less fit strain mCherry. The scale bar is 1 mm. The white lines are the positions of the domain walls located with our image analysis package [34]. We tracked the angular growth of sectors sweeping through a less fit strain, ϕ − ϕ0, as a function of ln(R/R0) to obtain . Right: 40 traces of each strain sweeping through mCherry from one set of agar plates. The translucent lines are the individual traces, the solid lines are the mean angular growth 〈ϕ − ϕ0〉, and the shaded area is the standard error of the mean. The slope of the mean angular growth is
