WebOf particular interest following all results presented above is the similarity between PC95, a mutant of the replicase NIb gene, and CLA11, a mutant of the VSR HC-Pro gene. These two mutations led to close fitness values ( Fig. 2A) , but also resulted in significantly similar gene expression profiles (Fig. 4B ).

But perturbations whose magnitude exceeds a certain threshold will break out of the canal, moving the developmental process into uncharted territory.
