The confusing part is "that" in the second sentence. It's hard to tell if you are referring back to the first statement, or if you're referring to what you will say next. I guess you are referring back to the original statement, so here's my rewrite: Is being a good cook something you inherit? I think you could say that to some degree. On the other hand, a person's upbringing which allows him or her to be exposed to many examples of good cooking may also have something to do with that person ending up being a good cook.

I believe what you're trying to say is something like this: "Is being a good cook something you inherit? I think I can say that, in some ways, a person's upbringing allows him to be presented to many opportunities in which he will be able to practice his cooking skills and, therefore, become a 'naturally good' cook. I believe these circumstances have something to do with the end result of him becoming such a good cook." That last line you could change the word "good" for "talented". If it's not along these lines what you were trying to say, just tell me and I'll try to rephrase the paragraph. Hope that helps =]
