Phenotypic range
WebIn ecology and genetics, a reaction norm, also called a norm of reaction, describes the pattern of phenotypic expression of a single genotype across a range of environments. One use of reaction norms is in describing how different species—especially related species—respond to varying environments. WebDec 6, 2024 · The phenotypic ratio is the number of times a specific combination of alleles appears in the predicted phenotypes of any offspring. Genetic information relating to the studied trait must be known. It is also possible to work out which parent alleles are dominant or recessive by studying the phenotypes of their offspring.

WebPhenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes. WebThe phenotypic ratio is therefore 13:3. This type of epistasis is sometimes called dominant suppression, because the deviation from 9:3:3:1 is caused by a single allele that produces a dominant...
