List of parameters in the model
Parameter Range Description
m -1 to 1 Determines mating system. Disassortative: m < 0, random: m = 0, assortative: m > 0. Mating becomes increasingly random as m approaches 0
b 0 to ∞ Benefit of receiving cooperation
c 0 to ∞ Cost of performing cooperation
x 0 to ∞ Number of additional offspring produced when mating partners have different recognition locus genotypes
N 2 to Population size Patch size; assumed to be even. Population size was set at 10,000 in all simulations
k 2 to ∞ Number of possible recognition alleles
r 0 to 0.5 Recombination rate between the recognition and behaviour loci
d 0 to 1 Probability that offspring disperse from the natal patch
μ 0 to 1 Mutation rate of both loci
h 0 to 1 Dominance of the cooperative allele; heterozygotes cooperate fully when h = 1, partially when 0 < h < 1, and never when h = 0
