Figure 7From: A Boolean gene regulatory model of heterosis and speciation Schematic representation of the definition of environments and their corresponding modules. The two shaded sub-networks are the modules that have been associated to two specific environments (see top). In an ideally adapted network, under Environment 1 in steady state all nodes of Module 1 are ON, while all nodes of Module 2 are OFF, while under Environment 2, Module 1 is OFF and module 2 is ON. Not all nodes are members of modules.Back to article page
