Pairwise invasibility plot
WebOct 19, 2024 · The full pairwise invasibility plot (PIP ) shows that for high resident ability all lower-ability mutants do better than residents, while some high-ability mutants can invade when the resident ability is low (figure 2d). Figure … WebThird, a fitness minimum where disruptive selection will occur and the population branch into two morphs. This process is known as evolutionary branching. In a pairwise invasibility plot the singular strategies are found where the boundary of the region of positive invasion fitness intersects the diagonal.
