Axanthic Chocolate Superarctic Anaconda is a combination of the recessive swiss chocolate mutation, the recessive axanthic mutation, the homozygous incomplete dominant superarctic mutation and the heterozygous incomplete dominant anaconda mutation. This combination is born a very dark colour, almost black, with slight blue hues over it. The swiss chocolate gene creates a darker headstamp due to the higher concentration of melanin on the head. The anaconda mutation reduces the dorsal pattern.
