Fig. 3: Sweep probabilities for alternative growth models.
From: Selective sweep probabilities in spatially expanding populations
A Populations expanding in 3D such that mutants expand within the expanding wildtype population (our main model, orange); proliferation is restricted to the boundary (purple); or the population radius is fixed at x0 (red). For the fixed population size, we set μ = 0.23 × 10−5 and x0 = 20 (solid curve), 15 (dashed), or 10 (dotted). In the case of an expanding wildtype, we set cwt = 0.15. B Well-mixed populations with exponential growth (green) or fixed total population size and logistically growing mutant (brown). We set rwt = 0.01 and μ = 10−4 (solid), 10−5 (dashed), or 10−6 (dotted). The fixed population size is N0 = 50, 000. Formulas for all curves are summarised in Supplementary Table S2.
