Final answer:
Gene-environmental protection involves preventing exposure to harmful environmental factors for individuals with genetic predispositions to reduce disease risk.
Explanation:
Gene-environmental protection refers to measures taken to prevent individuals with genetic predispositions from being exposed to harmful environmental factors that can exacerbate the risk of disease. In the context of chronic lung disease, restricting occupational exposure for those with genes predisposing them to the condition is an example of gene-environmental protection. This approach aims to minimize the impact of environmental triggers on individuals with genetic susceptibilities.
