From: Assortative mating and gene flow generate clinal phenological variation in trees
Variations in within-population allelic covariation ( θ W ) and genetic variance ( V W ) under different evolutionary scenarios. θ W and V W were monitored under three different strengths of assortative mating and two levels of environmental cline. All simulations were conducted under the island migration model with moderate gene flow (Nm = 5.1). The red line indicates strong assortative mating (ρ = 0.8), the blue line moderate assortative mating (ρ = 0.3), and the black line random mating (ρ = 0). Each line represents the mean of 50 independent replicates for each evolutionary scenario.
