Effect of cooperation on genetic diversity during a peak shift. a The relative increase in diversity, D R (c = 0.6), as a function of the selection coefficient, s, and the double mutant coefficient, H. Cooperating populations are more diverse throughout the parameter range. Data is averaged over ≥200 simulations per parameter set. b The average genetic diversity (taken over ≥200 simulations) in a cooperative population (blue line) is higher than that of a non-cooperative population (red line) at almost every time point. Parameter values are: (b) s = 0.05 , H = 5; (a, b)  n = 1,000 , k = 10 , μ = 10−5 , r = 0.01 , b = 1.2 , m = 0.01
