Patternless

Genetics:  Simple Recessive:

This is a simple recessive morph that has been around since the mid 90s.  They hatch out yellow or tan with light speckling on the back.  As they grow, the speckling disappears, giving them a "patternless" appearance.  When these were first introduced, they were commonly called "leucistic".  This morph also has albino forms, which brightens up the coloration considerably.
