Jeff Holloway (of Holloway Herps) has a calico kenyan. You can see it on his webpage:
There are several things at the genetic level that can cause the 'calico' phenotype. Some of these can be inheritable while others are not. I'm not a geneticist so hopefully someone else will chime in. If not, shoot me an e-mail.
