going by the "receiving money when people die" thing, I'd say its anything your relatives give to you. I'm sure in a biological science context people mean only genetic/biochemical things (biochemical - e.g. heroin addiction), but my point is that it's difficult to separate out the truly biological ones from the learned ones in most cases.

That's a fine point to make - separating out variables is hard. But when talking in a biological context, you're going to confuse people if you use the colloquial definition of "inherited".
