No, there is a certain Black Eyed gene that shows through even in Albinos, Siamese, etc. They are not commonly seen in the pet trade yet. Go to the link Rhasputin provided, maybe that will help you understand it a little better than I can explain it.

In order to make a BES (Black Eyed Siamese), you will need to find someone who carries one of the Black Eyed lines, not just any Black Eyed rat will work. It is a certain line.
