  1. Abbreviations: Chr., the number of simulated chromosome; Est., the estimate of parameter; Par., the true parameter value in simulations; Pos., position (the distance (cM) between the QTL and the first marker on the same chromosome); Power, the percentage of the QTL that is detected correctly to be significant at 0.05 and/or within the 95% confidence interval; QTL, quantitative trait locus.
  2. Note that am, dm, ae and de are maternal additive and dominance effects, endosperm additive and dominance effects, respectively. The s.d. indicates the standard deviation for the estimate of the true parameter value.
