Mechanisms in variability
... Note that the reaction norms are not identical. When phenotypic differences between genotypes vary (differ) between environments, we say there is a genotype x environment interaction. One example of this is the response of the plant world’s “lab rat”, Arabidopsis thaliana, to cold treatment. Either ...
