Skullface Woma Arctic Anaconda is a combination of the dominant skullface mutation, the polygenic woma trait, the heterozygous incomplete dominant arctic mutation and the heterozygous incomplete dominant anaconda mutation. Woma is a polygenic trait that creates a banded pattern. The lack of head pattern is caused by the skullface mutation. The arctic mutation creates a higher concentration of melanin at the borders of the saddles and surrounds them with white lines. The anaconda mutation removes some of the dorsal pattern.
