¹Abbreviations and assumptions. Standard error of estimated QTN location by simulation, as a function of number of G_2R families (F) within given total mapping population size, (N), and number of markers spanning the QTL (k). Location of the QTN within its confidence interval (L = 0.57); allele substitution effect at the QTN = 0.2 in standardized units
