The Mack Snow is best described as a type of axanthic, which is a genetic term given to an animal exhibiting reduced yellow pigment. As babies they emerge from the egg having white bands in place of the typical yellow bands. The adults display a decreased amount of yellow pigment and their background coloration would be best described as a pastel yellow hue. The mutation has proven to be a co-dominant trait and the super form regarded as the Super Mack Snow has stark white background coloration with a black spotted pattern. We are working with a large group of Mack Snows and have been producing pure Mack Snows as well as many combinations.
