Offspring Survival Probability S as a Function of Genetic Difference H.

For all the results presented in this paper, viability is not reduced if gametic genomes differ only by θ₀ = 0.05 or less (this is an adjustable parameter in the model). If gamete genomes differ by more than 5%, offspring survival probability is reduced linearly to eventually reach 0 for a threshold amount θ of genetic difference (θ = 0.6 in this graph and in all simulations presented here).
