Genes as Cues of Relatedness and Social Evolution in Heterogeneous Environments
Fig 5
Illustration of the information contained in genetic cues.
Panel (A) shows the conditional probability of being in habitat 1 (with r1 = 0.05) for an individual possessing cue allele x1 (blue curves, q11) versus cue allele x2 (red curves, q12). The probability is given as a function of the recombination rate ρ between cue and modifier loci. The three cases are from Fig 2, with different rates of between-habitat migration m12 = m21 = m = 0.01, 0.05, 0.10. The blue lines in panels (B) to (D) show logistic regressions of habitat 1 on the liability a0+ag x in eq (5), for the individual-based simulations in Fig 4B to 4D (with m = 0.10 and ρ = 0.5). The distributions of this liability are shown in gray, and the vertical blue and red lines indicate ‘typical’ low and high values (mean ± sd for (C) and (D)). See S1 Text for further explanation.
