Rosy boa morphs- Albinos, Anerys, Axanthics, and Snows

This information should all be covered (and more accurately) in Jeremiah's book.

---Mutation background
There are various mutations that snakes can have that affect the way they look. I'm only gonna talk about three.
Albinism - What we call Albinism is not actually the lack of all color, rather it is the lack of only dark pigment. Depending on certain underlying factors, the eyes are sometimes affected.
Anerythrism - This is the lack of all red coloring. The snake ends up looking bluish grey.
Axanthism - This is the lack of all red and yellow colorings. Looks similar to anery.

We label snake mutations as albino/anery/axanthic based on how they look to us rather than on any actual genetic testing. Axanthism and Anerythrism can be impossible to distinguish, so naturally there are disagreements about it.


---Known rosy mutations
There have been several of these mutations found in rosys. They are:
*Albino White Water - an albino rosy was found in white water canyon in 1993. Eyes are not affected.
*Albino Limburg - an albino was found somewhere in the temecula valley and then purchased by Randy Limburg. Only albino rosy with red eyes.
*Albino Harquahala - produced in captivity from wild caught stock. Quite rare. I only know of 2-3 people who have these.
*Albino Borrego - found in the wild. Currently only 3 in existence.

Albino White Water

*Anery Borrego - although quite rare, probably the most common of the rosy anery/axanthics.
*Axanthic Limburg - Most people call them anery, but they're probably axanthic. The original was purchased by Randy Limburg.
*Axanthic Morongo - Appear to be axanthic. Very rare.
*Anery pioneertown - Just produced in 2008 from locality captives.

---Snows
If you breed animals with two different mutations together, you will end up with offspring that are carriers of both mutations. Breeding two of these "double carriers" together gives a 12% chance of producing an animal with BOTH mutations expressed.
A "snow" is an animal with both Albinism, and anerythrism (or axanthism) expressed. Naturally they are hard to produce, and very expensive.

So far, the following have been produced:
*Carlson Line Snow - WW albino and Borrego anery. They have a light yellow pattern, and dark eyes.
*Limburg Snow - Limburg albino and Limburg axanthic. Solid white with red eyes.
*Snow White - WW albino and Morongo axanthic. Solid white with solid black eyes.

People have also crossed some of these morphs with various other localities, to bring out extreme colors or traits. One of the many interesting crosses is Kent's cross of the WW albino with a really bright Anza-Borrego. He then bred the Hets back to each other and produced this animal.
