Bifurcation Analysis in Population Genetics Model with Partial Selfing

𝑢₁₁=0.5, 𝑢₁₂=1, 𝑢₂₂=0, 𝛽=0.6, and 𝛾=10. A saddle-node bifurcation happens for (𝑝^∗,𝐹^∗,𝜉^∗), where 𝑝^∗=0.7916666665,𝐹^∗=0.4285714286,and𝜉^∗=0.5372023808. Two new polymorphic phenotypic equilibria are created for 𝜉<𝜉^∗ and disappear for 𝜉>𝜉^∗.
