MLEs of the position and effect parameters for a QTL without maternal-zygotic interaction effect under simulation schemes of different heritabilities (H2) and sample sizes for each backcross (n).

The numbers in the parentheses are the square roots of the mean square errors of the MLEs calculated from 100 simulation replicates. The power to detect the imprinting effect of a QTL and the Type I error rate for the detection of maternal-zygotic interaction effect were also given. Note: Simulation schemes: (1) H2 = 0.1 and n = 100, (2) H2 = 0.1 and n = 400, (3) H2 = 0.4 and n = 100, and (4) H2 = 0.4 and n = 400, where n denotes the sample size of each of the four backcrosses. The residual variance σ12, σ22, σ32 and σ42 are 0.20, 0.09, 3.80, 10.89 for H2 = 0.1, and 0.03, 0.02, 0.63, 1.82 for H2 = 0.4, respectively.
