Phenotypic canalization
WebCanalization thus reduces phenotypic variation, presumably through some homeostatic mechanism. Although canalization has been viewed as a developmental constraint on … Canalisation is a measure of the ability of a population to produce the same phenotype regardless of variability of its environment or genotype. It is a form of evolutionary robustness. The term was coined in 1942 by C. H. Waddington to capture the fact that "developmental reactions, as they occur … Zobraziť viac Waddington used the concept of canalisation to explain his experiments on genetic assimilation. In these experiments, he exposed Drosophila pupae to heat shock. This environmental disturbance caused some … Zobraziť viac Neither canalisation nor robustness are simple quantities to quantify: it is always necessary to specify which trait is canalised (robust) to which perturbations. For example, perturbations can come either from the environment or from mutations. … Zobraziť viac In 1998, Susan Lindquist discovered that Drosophila hsp83 heterozygous mutants exhibit a large diversity of phenotypes (from sexual combs on the head, to scutoid-like and … Zobraziť viac 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 … Zobraziť viac Understanding variability is an extremely important aspect of understanding natural selection and mutations. Variability can be classified into … Zobraziť viac • Developmental noise • Phenotypic integration • Phenotypic plasticity Zobraziť viac
