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… WebAug 1, 1998 · When the expression of a trait is well canalized, most genetic and environmental variation has no, or very little effect on the phenotype, so that a population remains phenotypically uniform even if it contains substantial genetic heterogeneity, or is exposed to wide fluctuations of the environment.
