The network model for the gap gene system of Drosophila melanogaster (reproduced from [20]). (a) Network representation of the regulatory interactions between four gap genes (gt, giant; hb, hunchback; kni, knirps; Kr, Krüppel). (b) Corresponding matrix W. (c) graphic representation of the gene expression states of each gap gene over three successive time steps of a sigmoidal function similar to (3) where a filled box denotes ‘on’ (1), and an open box denotes ‘off’ (−1).
