Contour plot of the theoretical log-likelihood function. The true parameters of the likelihood problem were (A) p₁ = p₂ = 0.5, D^sire = 0.05, D^dam = 0.15; (B) p₁ = 0.5, p₁ = 0.4, D^sire = 0.05, D^dam = 0.15; (C) p₁ = p₂ = 0.5, D^sire = 0.245, D^dam = 0.05, and (D) p₁ = 0.5, p₁ = 0.4, D^sire = 0.245, D^dam = 0.05. Expected genotype frequencies based on the true parameters were considered, e.g., $n_{AA,AA}=(1/4+D^{sire})(D^{dam}+p_1{p}_2)$.
