Snow is the combination of Amelanistic (Amel) and Anerythristic (Anery).
Amel is the lack of black pigment, and Anery the lack of red. This leaves the snake with only white colouring left.
As hatchlings, they are pink and white, and as adults colours can vary. Some can be fairly pink (sometimes called Bubblegum snow corns) and some can be almost solid white.
Most older snow corns can show yellow around the throat area.
Our Snow girl, Isis, is the first snake we had. We loved her so much, we got another, and another.. And the rest is history!
