Fig. 2From: Neutral genomic signatures of host-parasite coevolutionParasite and host alleles of genotype two are plotted against each other for the GFG model over time by numerically solving (1) and (2) for the following parameter values (being equivalent for both genotypes): \(b=1, d=0.9, \delta =0.01, \beta =0.00005, c_{H_{1}}=c_{P_{2}}=0.05\) and \(c_{H_{2}}=c_{P_{1}}=0\). The initial conditions are H1=H2=4150 and I11=I12=I21=I22=415. The selection coefficients s are given by a 1, b 0.9, c 0.6 and d 0.3. The parametric plots are shown for a 100, b 500, c 120 and d 96 time steps, which are the minimum amounts of time to complete one orbit of the final limit circle (a), come close to the fixed point (b), (c), or to reach the fixed point (d). The initial and fixed points are colored in black and red, respectivelyBack to article page
