Genetic correlation (Rho) between a Gaussian character and a mixture trait for a two-component mixture, as a function of the mixing proportion (), for different combinations of ρ_homo, genetic correlation in absence of mixture, and λ, heteroscedasticity factor. From top to bottom: (1) ρ_homo = 0.7, λ = 1.5 (open squares); (2) ρ_homo = 0.7, λ = 2 (dotted line); (3) ρ_homo = 0.3, λ = 1.5 (solid line); (4) ρ_homo = 0.3, λ = 2 (open circles).
