Simulated data for total proportion retained (p)= q1q2 = 0.01, 0.10, and 0.30, and estimated optimum and decorrelated constrained multistage linear phenotypic selection indices (OCMLPSI and DCMLPSI, respectively) responses (Ȓ1, Ȓ2, and Ȓt = Ȓ +2) and single-stage constrained linear phenotypic selection index (SCLPSI) responses (Ȓ0.01, Ȓ0.10, and Ȓ0.30) for four simulated selection cycles in a two-stage breeding scheme.
