What is meant by canalisation?

Definitions of canalisation. the production of a canal or a conversion to canals. synonyms: canalization. type of: production. the act or process of producing something.

What is a highly canalized trait?

Canalized traits are phenotypically expressed only in particular environments or genetic backgrounds and become available for natural selection, a mechanism that can lead to the assimilation of novel traits.

What is Canalizing selection?

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.

What is canalization genotype?

Canalization implies that a genotype’s phenotype remains relatively invariant when individuals of a particular genotype are exposed to different environments (environmental canalization) or when individuals of the same single- or multilocus genotype differ in their genetic background (genetic canalization).

What is canalisation in sociology?

Manipulation refers to the way in which parents deter of encourage behaviour on the basis of appropriateness in regards to gender, Canalization refers to the way in which parents channel the child’s interests in activities or toys in conjunction with gender as deemed appropriate. …

What is a canalisation officer?

THE CANALIZATION OFFICER IS AN INDEPENDENT SOCIAL WORKER ENTRUSTED WITH THE FOLLOWING FUNCTIONS. 1. Regulating the stay of the children in an alternative care in the area of jurisdiction. 2. Managing and facilitating the movement of the children within the Child and youth care centers.

What is developmental canalisation?

Canalization is the tendency for development of a specific genotype to follow the same trajectory under different conditions (different environments or different genetic backgrounds), while developmental stability is the tendency for the development of a specific genotype to follow the same trajectory under the same …

What causes canalization?

Canalization is a property of individuals that is almost always measurable only at a population level [8]. In genetic terms, a genetic factor increases canalization if, all else being equal, it reduces the phenotypic variance [35].

What does canalisation mean in sociology?

Who invented the canalisation?

The term was coined in 1942 by C. H. Waddington to capture the fact that “developmental reactions, as they occur in organisms submitted to natural selection…are adjusted so as to bring about one definite end-result regardless of minor variations in conditions during the course of the reaction”.

What is canalization child development?

What is the role of gender in feminism?

Feminists claim that gender stereotypes serve to uphold patriarchy and place boundaries upon women’s lives. This serves the interests of men because it links female self-worth with external beauty rather than actual achievement.

What is canalization in biology?

CANALIZATION: “In evolutionary genetics, canalization is a mechanism used for maintaining a more constant phenotype by containing and repressing genetic variation .”.

Is there a role for the canalization heuristic in genetic assimilation?

“Genetic assimilation can occur in the absence of selection for the assimilating phenotype, suggesting a role for the canalization heuristic”. Journal of Evolutionary Biology. 17 (5): 1106–10. doi: 10.1111/j.1420-9101.2004.00739.x.

What is the difference between canalization and phenotypic plasticity?

Consequently, genetic canalization can be viewed as a particular kind of epistasis, and environmental canalization and phenotypic plasticity are two aspects of the same phenomenon. Canalization results in the accumulation of phenotypically cryptic genetic variation, which can be released after a “decanalizing” event.

What is the canalisation metaphor?

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.
