Effect is the measured change in genotypic mean resulting from substituting two Exeter alleles with two Dal alleles.
For marker intervals, this is the distance from the first marker followed by the total interval distance between the markers in parentheses.
§All reported effects are significant with an experimentwide type I error rate of p < 0.05 determined by permutation. Cells with data in italics indicate QTL detected with simple interval mapping (SIM) only while cells with data in bold were detected with SIM and confirmed with simplified composite interval mapping (sCIM). The rest were detected with sCIM only. The p-value for the sCIM is used as the level of significance when QTL positions are detected with both SIM and sCIM.
Significant with an experimentwide type I error rate of p < 0.01.
#Total effect is the sum of absolute values of effects. It predicts the range of progeny values.

Locus A was selected based on the presence of a significant QTL main effect. This locus was held constant while scanning the genome for the presence of Locus B for which there was a significant deviation from the predicted sum of additive effects at each respective locus pair.
Effects are reported as genotypic means for each of four two-locus homozygous classes. Lowercase signifies the presence of Exeter alleles and uppercase signifies Dal alleles.
