Webnorm-of-reaction. The norm of reaction of a genotype is at best only incompletely known. Complete knowledge of a norm of reaction would require placing the carriers of a given genotype in all possible environ- ments, and observing the phenotypes that develop. This is a practical impossibility. WebLecture Description. Reaction norms depict the range of phenotypes a single genotype can produce, depending on the environment. Reaction norms must fit within an organism's phylogenetic constraints. They can differ for different individuals within a population, but some traits differ very little based on the environment; some do not differ at all.

Web7 de dez. de 2010 · Conclusions: The pattern of associations between adult stature and age at menarche may be explicable as a norm of reaction that evolved according to predictions of life history theory. However, nonadaptive explanations are also plausible, especially for the positive association observed in industrialized societies. WebA norm of reaction is an array of phenotypes that will be developed by a genotype over an array of environments. The quantification of a norm of reaction is conceptually quite simple: one obtains a number of different genotypes (clonal pants are great for this) and grows each one in a variety of different environments (e.g., different nutrient, light, water conditions). WebAbstract. A standard norm of reaction (NoR) is a graphical depiction of the phenotypic value of some trait of an individual genotype in a population as a function an environmental parameter. NoRs thus depict the phenotypic plasticity of a trait. The topological properties of NoRs for sets of different genotypes can be used to infer the presence ... simplyvital health inc
