Fig 2. The interaction of evolutionary parameters affects the need for introgression to explain trait patterns.
G-XRF is shown as a function of internal branch length T2 − T1 and inheritance probability γ when reticulation time Tr = 0.1 coalescent units and population mutation rate θ = 0.01 (top row), and as a function of θ and Tr when T2 − T1 = 10 and γ = 0.5 (bottom row).
