We don't know enough about the genetics of bending to say much about it. So far all we understand is that in order to be a bender of a certain element, someone related by blood in their family before them must have had the element. Since the only airbender is Aang, all airbenders must come from him. Until it's shown that someone can become an airbender by being "spiritual" enough, we can't assume that.
