interactionist
approach may, therefore, be much more valid than either a biological or environmental theory alone.

What is the main idea of gene environment interaction?
Based on this concept, gene–environment interaction can be defined as “
a different effect of an environmental exposure on disease risk in persons with different genotypes
,” or, equivalently, “a different effect of a genotype on disease risk in persons with different environmental exposures.”
