Canalization describes the phenomenon whereby particular genotypes exhibit reduced phenotypic sensitivity or variation (i.e., increased robustness) in response to mutations and/or to environmental changes relative to other genotypes. Canalization is a variational property of genotypes: it implies a reduced potential or … WebThe concept of phenotypic plasticity defines the degree to which an organism's phenotype is determined by its genotype.

WebJun 12, 2024 · Organisms are faced with variable environments and one of the most common solutions to cope with such variability is phenotypic plasticity, a modification of the phenotype to the environment. These modifications are commonly modelled in evolutionary theories as adaptive, influencing ecological and evolutionary processes. WebJul 30, 2002 · One possibility, the answer that Siegal and Bergman propose, is that phenotypic robustness to genetic perturbation has been wrongly interpreted as adaptive canalization. They assume selection against lethals, in their context genes that do not settle on a stable gene expression.

WebJul 28, 2024 · Phenotypic integration and developmental canalization have been hypothesized to constrain the degree of phenotypic plasticity, but little evidence exists, probably due to the lack of studies on the relationships among the three processes, especially for plants under different environments.

WebMechanistically, canalization can be understood in terms of transmission patterns, such as epistasis, pleiotropy, and genotype by environment interactions, and in terms of genetic … WebGenetic canalization. In contrast to phenotypic plasticity, the concept of genetic canalization addresses the extent to which an organism's phenotype allows conclusions about its genotype. A phenotype is said to be canalized if mutations (changes in the genome) do not noticeably affect the physical properties of the organism. This means that a ...

WebJun 24, 2002 · Canalization evolves under stabilizing selection, except under a scenario in which an already canalized population is subjected to a new phenotypic optimum, at which point “decanalization” may occur temporarily. Such an occurrence may be related to the process of genetic assimilation.
