Graphical model representation. (a) The representation of conventional interval mapping as a graphical model. For an observed i, all candidate genotype sites j are considered. (b) The QTG model of a single regulator-target pair of genes (regulator is gene j and target is gene i). Subgraphs of (b) represent (c) cis-, (d) trans-, (e) cis-trans- cases, and (f) no genotypic effect, corresponding to the conventional BN. Colored and shaded nodes are observed.
