gene-environment interaction

A term used to indicate that an effect is due to a mixture of environmental factors (nurture) and genetic factors (nature). Most traits show gene-environment interactions, such as myopia, IQ test results, skin colour etc. Blood type and iris colour are predominantly genetically transmitted, whereas language is predominantly environmental. See biological-statistical theory; nativist theory.

In the current study, differences in performance across sites for the same line are environmental effects, and the interaction between the site and the line is a genotype-by-environment interaction (G x E).
As different behaviors were observed inbred lines according to the environments, indicated by the significant genotype-by-environment interaction, selection for specific environments was practicable for most traits.

Expressed in yet another way, the central concept of genotype-by-environment interaction is that of conditionality.
As additional research begins to clarify how specific genetic variants contribute to risk for AUDs, greater cross-talk between the twin literature, gene-identification studies, and studies testing for measured genotype-by-environment interactions will be critical to producing a more systematic research program aimed at understanding gene-by-environment effects for this critical and socially important condition.
Genotype-by-environment interactions can result from differential fitness of genotypes across environments, but also from environmental-related differences in fitness of individuals.
To this end, I performed a reciprocal-transplant experiment in the field and a greenhouse experiment using seed families (genotypes) from four demes to estimate genotype-by-environment interactions in establishment of individuals.
To test for genotype-by-environment interactions in seed germination and seedling survival I performed a reciprocal-transplant experiment between sites in native and degraded-forest habitats.
