Simulation design and genetic variance decomposition of different models.

aThe regression model that was used to generate the “core gene” in each module.
bThe average percentage of variation of genes in the module explained by the true model.
cThe average percentage of genetic variance explained by the first locus.
dThe average percentage of genetic variance explained by the second locus.
eThe average percentage of genetic variance explained by epistasis. In all modules, the heritability of the “core gene” is 0.6 and the average correlation of the module genes with the “core gene” is 0.5.
