From: Bayesian model selection for the Drosophila gap gene network
Gap gene network. Gap gene network showing regulatory interactions between maternal genes, Bicoid (Bcd) & Caudal (Cad), and gap genes (Knirps (Kni), Hunchback (Hb), Kruppel (Kr), Giant (Gt)). Two types of binding affinity parameters are shown - global (K) and edge-specific (K1,K2,K3). We also investigate evidence for Bicoid activation of Kruppel (shown as dashed arrow)
