Blizzard Corn Snake
A blizzard corn is produced by firstly crossing an Anerythristic type "B" ( known as a Charcoal corn ) with an Amelanistic ( or snow ) corn. You then raise the hatchlings and breed these together. If you are lucky then the genes for Anerythristic type "B" and Amelanism will be expressed in one or more of the offspring. This animal with both genes expressed is your blizzard corn. The chance of producing one is 1 in 16. However you do not have to do this as several breeders have spent the time and energy already.
Blizzard corns are often pure white but sometimes there is a very small amount of pattern that shows through. In my experience they are good feeders and quick growers. For some reason they are often feisty. Nevertheless they are one of the most sort after phase of corn available today.
