^a Epi.: the paired QTLs (in the parenthesis) involved in epistatic effects; Pos. i and Pos. j: the positions of the QTLs measured by the distance (cM) between a QTL and its corresponding first marker on the same chromosome; AA: additive-additive effect; AD: additive-dominance effect; DA: dominance-additive effect; DD: dominance-dominance effect; Power: the percentage of the QTL pair that is identified correctly; Par. (parameter): the true parameter value in simulations; Est.: the estimate of parameter; SD: the standard deviation of the estimate from the true value that is listed in the parenthesis where applicable; E1, E2, and E3: three epistases; I (Model I) and II (Model II): model (1) (silkworm F₂ model) and the normal chiasmate F₂ model, respectively.
