  1. NS = number of sires; NO = number of offspring per sire; σ A int 2 = additive genetic variance of breeding value for intercept (true value = 0.3); σ A sl 2 = additive genetic variance of breeding value for slope (= macro-environmental sensitivity; true value = 0.05); σ A v 2 = additive genetic variance for environmental variance (= micro-environmental sensitivity; true value = 0.10); ρ A int , A v = ρ A int , A sl = ρ A sl , A v = 0; Np = number of replicates with covariance structures forced to be positive definite.
