Table 1 List of parameters in the model

From: Crozier’s paradox revisited: maintenance of genetic recognition systems by disassortative mating

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
