Rather than being directly hereditary from a parent, Crohn’s disease has some genetic inheritance. This means that the disease could be in your genes as opposed to having been passed down through generations. If you have a close family member (parent, sibling, aunt, uncle, etc) with Crohn’s, you are more likely to develop the disease, but not everybody with Crohn’s disease in a first-degree relative will also get Crohn’s disease.
