Can food allergies be passed down from family member to family member?!

Can food allergies be passed down from family member to family member?

My mom has food allergies and she is supersticious that I have them too. The allergy is shellfish and she formed it later in her life---around 39 i think? She won't let me have any, but i really don't think i'm allergic to shellfish because i went to this place where they cook right in front of you, and the were making shrimp and steak and chicken on the same grill stove thing. And shrimp "juice" is bound to have touched the steak (which i had) so i really don't think i'm allergic. So my question is: Can my mom's allergies be given to me even though she formed the allergy around 1 or 2 years AFTER i was born? please no guesses, i want you to for sure know. thank you

My allergist told me people's predisposition to allergies can be hereditary. In my personal case, I am highly allergic to a specific mushroom that is extremely common where my mother is from (she's from another country); however the mushroom is uncommon where I was born and raised. I do not appear to be allergic to any other types of mushroom. I didn't develop my allergy until I was well into my 40s and my mother's family has a history of allergies (all developed later in life), but not food allergies. I don't think it's a done-deal that you will develop a food allergy - you may develop an allergy to something else. If you really want to know for sure, go to a doctor and ask to be tested.
