Degrees of freedom, percentage of variance explained by the model, and P values derived from χ2 tests were generated by fitting the QTL model with ANOVA. The penalized whole-model LOD score (pLOD) was derived from stepwise model selection, where models that increase pLOD are retained. Significant interactions between the cytoplasm and QTLs were indicated in the formula; statistics for the interactions are reported in Supplemental Table 4.
