gene-by-environment interaction

Gene-by-environment interaction occurs when your genes influence how you respond to different environmental factors, meaning that the effect of a particular gene can change depending on your environment. For example, a person might have a genetic predisposition to develop a certain condition, but whether it actually occurs can depend on environmental influences like diet, stress, or exposure to toxins. Essentially, this interaction shows that neither genes nor environment alone fully determine traits or health outcomes; instead, they work together, with your environment sometimes amplifying or reducing genetic effects.
