gene-environment interactions

Gene-environment interactions refer to how our genes and the environment we live in work together to influence our traits and health. Genes provide the blueprint for our physical characteristics and susceptibility to certain conditions, while environmental factors—like diet, lifestyle, and exposure to toxins—can affect how those genes are expressed. For example, a person may have a genetic predisposition for a condition, but whether they actually develop it can depend on their choices and surroundings. This interaction highlights the complex relationship between our biology and our life experiences.
