Genes as Cues of Relatedness and Social Evolution in Heterogeneous Environments
Fig 3
Trait evolution plots for dimorphisms.
In each example, the shaded region shows where a dimorphism z1, z2 can be maintained, the arrows indicate the direction and magnitude of the selection gradient Eq (7), and the dots show evolutionarily equilibrium dimorphisms. The examples differ in between-habitat migration rate m12 = m21 = m and rate of recombination ρ. (A) m = 0.05, ρ = 0.001; (B) m = 0.05, ρ = 0.5; (C) m = 0.10, ρ = 0.001; (D) m = 0.10, ρ = 0.5. Other parameters: N1 = 20 and N2 = 2, W1 = W2 = 0.5, b1 = b2 = 3.0, c1 = c2 = 1.5.
