[i] The table shows for how many of the detected pairs that a marginal effects model including additive and dominance effects (A + D) and an epistatic QTL model (E) were selected, based on a model selection randomization test. The table also gives the number of times two, one or none of the QTL in the detected pair also was detected with forward selection (F) using a marginal effects model.
[ii] QTL, quantitative trait loci.
