Reaction norm

But the full complexity of the norm of reaction is a function, for each genotype, relating environmental factor to phenotypic trait.

One advantage of plants is that the same genotype, such as a recombinant inbred line (RIL), can be repeatedly evaluated in multiple environments, or a multi-environmental trial (MET).

[6] Popular non-scientific or lay-scientific audiences frequently misunderstand or simply fail to recognize the existence of norms of reaction.

This limited conceptual framework is especially prevalent in discussions of human traits such as IQ, sexual orientation, altruism, or schizophrenia (see Nature versus nurture).

Popular conception of genotype/phenotype interaction The problem with this common simplified image is not that it does not represent a possible norm of reaction.
