Canalized gene expression
WebWe observe that natural selection acts to preserve canalized gene expression in populations of killifish that are most tolerant to abrupt salinity change a nd that these populations show the least variability in their transcription of genes enabling plasticity of the gill. We fo und that genes participating in this highly canalized and 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…
