Answer

Because allergic rhinitis has a significant genetic component, [41] a positive family history for atopy makes the diagnosis more likely.

In fact, a greater risk of allergic rhinitis exists if both parents are atopic than if one parent is atopic. However, the cause of allergic rhinitis appears to be multifactorial, and a person with no family history of allergic rhinitis can develop allergic rhinitis.
