Genes and the environment probably both play a role in the development of allergies.
Is it true that genes and the environment probably both play a role in the development of allergies?
Yes. Genes and environmental factors both play critical roles in the development of allergies, interacting dynamically to influence disease risk.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The claim is specific, empirical, and contestable, passing Step 0. The retrieved literature consistently supports the role of both genetic susceptibility and environmental exposures (as well as their interactions) in various allergic conditions such as asthma, allergic rhinitis, and food allergies. Therefore, the evidence strongly supports the claim.
