Genetic canalization is defined as the capacity of an organism to undergo a normal development even when the genome is altered by mutations. Currently, three main hypotheses are prone to explain the apparition of such a process: evolutionary, congruent and intrinsic. To test these hypotheses, I chose to study gene regulatory networks. To this end, I used a theoretical model, ran in silico simulations, and analyzed the genetic architecture by using quantitative genetics tools. I first studied the evolutionary behavior of the model, and its capacity to respond to stabilizing selection. In addition to the sensitivity analysis to model parameters, I evidenced the absence of mutation-selection-drift equilibrium after several thousand generations...
