Do adopted children grow up to fart similar to their guardians' farts or more similar to their parents' farts? (Nature vs Nurture question)

After watching some crows/ravens uttering english words in some video.. I somehow got to wondering if our auditory rear-flatulence is mimicked after our influences or if it’s more of a genetic call.

That is: Do we “sound out” our farts according to what we’ve heard in the past? For some reason, I suspect the sound of our farts are mimicked after “fart role models.” Perhaps people we laughed about when we were kids. Most likely our parents or legal guardians. I could be wrong though.

I would like to hear read from a contrast between adopted and non-adopted people. Do your farts sound similar to your guardians’ farts even if you aren’t biologically linked?
