Table 2 Simulation parameters
SymbolDescription and settings
NPopulation size (N = 500), held constant.
GTotal number of generations (G = 5000)
μ, UPer-site and per-genome rates of mutations (μ = 10−6, U = 0.06), Poisson distributed and uniform across the genome
RPer-genome rate of recombination (R = 0, R = U, R = 5U), Poisson distributed and uniform across the genome
LGene length (L = 500 codons)
BNumber of genes (b = 4)
δTract lengths of gene conversion (δ = 30 codons), exponentially distributed
spur, sdir, sfdsSelection coefficients of purifying (spur = 0.1), directional (sdir = 0.01), and frequency-dependent (sfds = 0.01) selection
n, fSample size (n = 30 individuals), taken at every f = 50 generations
w, WFitness of a codon and an individual haploid genome
π, KAverage pairwise nucleotide differences within and between populations
