Change of the proportion of the epigenetic variance over the total genetic variance ( R _e ²) as a function of the dominant genetic effect due to the interaction between the original allele and epiallele. The total and epigenetic genetic variances are calculated by assuming population genetic parameters (p, q, u, D_1e, D_2e, D₁₂) ≡ (0.4, 0.6, 0.2, 0.01, 0.01, 0) and quantitative genetic parameters (a₁, a _e , d_1e, d_2e, d₁₂) ≡ (0.08, 0.12, d_1e, d_2e, d₁₂) (allowing d_1e, d_2e and d₁₂ to change).
