\(P_{Mut}\) (black line), \(P_{1}\) (red line) and P _Con (blue line) for the trans-acting suppressor mutation. a Probabilities increase with increasing vN ₀ for R _m  = 6, m = 0.95 (solid lines) and for R _m  = 12, m = 0.98 (dotted lines), and w = 1. b Probabilities increase with increased intrinsic growth rate R _m (for m = 0.95, w = 1, vN ₀ = 0.1). c Probabilities decrease with increased Y-drive m (for R _m  = 6, w = 1, vN ₀ = 0.1. For all plots, h ₀ = 0.05. d Probabilities decrease with lower fitness \(w\) (for R _m  = 6, m = 0.95). The deterministic model shows that the population will be eliminated for w ≤ 0.61. For all plots, h ₀ = 0.05, vN ₀ = 0.1. The error bars at low R _m and w show the standard error for simulations (averaged over \(10^{6}\) runs, N ₀ = 10⁶), when the branching process model does not apply; if not shown, error is within thickness of plot line
