Fig. 1From: Why and how genetic canalization evolves in gene regulatory networksExpression level of gene i as a function of the strength of regulation: \(S_{i_{t+1}}=f\left (\sum _{j} W_{ij} S_{jt}\right)\). The dashed line represents the slope d f/d x=1 at the point f(x)=0; the dotted line stands for the gene constitutive expression a=0.2Back to article page
