The etiology of asthma is still very unclear, but genetics may indeed be related to bronchial asthma to some extent. Currently, a lot of research data indicates that the incidence rate of bronchial asthma is higher among the relatives of patients than in the general population, and the closer the familial relationship, the higher the incidence rate and potentially more severe the condition could be. In layman's terms, this means that if our parents have bronchial asthma, then the likelihood of their children having bronchial asthma is higher than in the general population. However, this is not absolute; it does not mean that if a parent has bronchial asthma, their children will definitely have it. The relationship is not very certain, and the genes related to bronchial asthma are also not very clear at present. Bronchial asthma is also related to many other factors.
