Variations in mean population genetic values at different latitudes under multiple scenarios. The value for each latitude is the average of the five mean genetic values for the populations concerned at generation 300. All scenarios (except the selection scenario, dashed line) were conducted under strong assortative mating (ρ = 0.8). Red line: steep environmental cline (kE = 2), island migration model, moderate gene flow (Nm = 5.1). Purple line: very steep environmental cline (kE = 3), island migration model, moderate gene flow (Nm = 5.1). Brown line: steep environmental cline (kE = 2), island migration model, extensive gene flow (Nm=10.2). Red line with open circles: steep environmental cline (kE = 2), stepping stone migration model, high gene flow (Nm=5.1). Dashed line: random mating, divergent selection ( <a onClick="popup('http://www.biomedcentral.com/1471-2148/12/79/mathml/M38','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2148/12/79/mathml/M38">View MathML</a>), strong stabilizing selection (ω2 = 5), without assortative mating. Each line represents the mean of 50 independent replicates for each evolutionary scenario.
