Webmization, quantitative traits, reaction norm. Received February 22, 1991. Accepted August 6, 1991. A reaction norm describes the pheno-types that a genotype can produce across a range of environments (Woltereck, 1909; Johannsen, 1909, 1911). Ever since Schmalhausen (1949) introduced the con-cept of reaction norms to modem studies 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.
