Figure 4

Allelic effects over coevolutionary time. Top row: Phenotypes zH (red) and zP (blue) simulated over coevolutionary time in the phenotypic-difference (left) and phenotypic-matching models (right). Middle row: Coefficients estimated under the host-only model (7) (black is β0, solid red is βHi, dashed red is βH1,H2). Bottom row: Coefficients estimated under the host–pathogen model (9) (black is β0, solid red is βHi, dashed red is βH1,H2, blue is βPi, dashed blue is βP1,P2, purple dashed is βHi,Pj). Because epistatic and G × G interactions are absent in the phenotypic-difference model, their allelic effects all overlap at 0 and hence are not all visible.
