Axanthic and Axanthic combos

 

Axanthic is a simple recessive gene, which first appeared in Mcdowelli (coastal), and later has been found in Harrisoni (Irian Jaya)
It has a marked reduction or absence of yellow pigment, and gives the animal a silver or grey look.

One off the more excluesive morphs is the snow, where axanthic is a part off, together with albino.
