Just like guitar playing, you can refine and refine and refine and work with what you have. I also think that, over time you start to sing what is more "true you" and true to your musical soul/style. If all goes well.You can extend the range of your voice over what you think it is. There is a physical genetic limit.
An incredible singer with a natural bass voice will never be able to hit the notes a natural soprano will hit. And that soprano will never command the bass register like the natural bass singer.
You can practice until you are blue in the face but you are born with your voice and there is only so much you can do.
This is where the other factors of a voice come in.
My point in my original post is do not try to be something you are not. If you are gifted with the voice you wish you had do the best with the one you have.
