For an essay I have to answer at university, with regards to alcohol, I have been asked to refer to both bioloigical and genetic evidence that influences alcoholism. I was always under the impression that genetics was part of the biological factor. Please can anyone help? I am guessing in my opinion that genetics is about inheritance and biological factors are regarding brain structures and chemicals within the brain which may effect it?
Thanks so much

Yes. Your impression is correct.

Thank you!
