Is cloning that simple?

Some quick thoughts on the possibility of doppelgangers:

By taking the SRY gene from the Y chromosome again and copy and pasting it as below, have I in fact just created a clone or doppelganger of the SRY gene?

And what happens if say I remove part of the protein code? Or add or rearrange it? Is this theoretically gene mutation?
