The canalisation metaphor suggests that some phenotypic traits are very robust to small perturbations, for which development does not exit the canal, and rapidly returns down, with little effect on the final outcome of development. But perturbations whose magnitude exceeds a certain threshold will break out of the canal, moving the developmental process into uncharted territory. For instance, the study of an allelic series for Fgf8, an important gene for craniofacial developm… WebEvidence that natural selection acts to preserve their canalized gene expression was obtained by referencing three populations that differ in their adaptive tolerance to salinity changes (Whitehead et al., 2011).
