Considering that identical twins are born with the same DNA, it is likely that they will have identical voices for the early part of their lives. However, outside factors, along with the way that their genetics change throughout their lives can alter that later on.

So, the answer to your questions is the enigmatic "sometimes, but not always."

I think the genetics don't change as much as how they use their voices. One might choose to sing, strengthening the vocal cords. The other might get a bad infection of the larynx and change the timbre of the voice drastically. I really have never heard of DNA changing.

@Serenitree: DNA doesn't physically change, but epigenetics describes how DNA expression changes. Of course, the situations you proposed would qualify as outside factors, as well.

@jason2: I'm going to yield to you on this, as I have never heard of epigenetics, but I will delve into this subject. Thank you. I am always happy to have something new to research. Nit that I go deep, but I do read enough to get an idea if it is something I might actually be able to grasp. Physics is so far out of my reach, I've given up in that, but I like reading about things I've never heard about.

@Serenitree: I've spent quite a bit of time myself on Wikipedia, learning about whatever catches my fancy... it's rather cool to encounter another kindred spirit.

@jason2: yes. It is. It's fun to meet someone who reads and learns, just for the joy of learning. Welcome to my world.
