Graphs inferred from two-trait QTL detection with pleiotropy. These graphs are a representation of the data from Table 2. The chromosome locations are illustrated in green with the APL chromosome number and the location in cM. The phenotypic traits are in blue and the proteins are in red associated with the spot number. A weight is given for links (in bold) when a pleiotropic QTL was detected. The size of the nodes (proteins or phenotypes) is related to the betweenness (calculated by Gephi), i.e. an indicator of centrality that identifies the most important nodes within a graph
