Genetic drift and selection in many-allele range expansions
Fig 12
The heterozygosity correlation function H(ϕ, L) (solid lines) obtained by averaging the results of 14 neutral eCFP and eYFP expansions from one set of agar plates at a variety of expansion distances L = R − R0.
The dashed lines are the theoretical fits of the heterozygosity with a constant Dw = 0.100 ± 0.005 mm. The theoretical curves track our experimental data, suggesting that a diffusive approximation to domain boundary motion is justified.
