Omitt State
What happens if, for some reason, the natural state gene is not active? This means the Volbur is not able to express ANY color on their back. The rest of their body might change color if they have any black on it. It can change into any color but black.
It is confirmed, that the black mask ALWAYS turns white! This creates some interessting phenotypes.
We discovered that an extra loci is working on the N Allele, which determines if the back turns white or disappears.
We called it Snowflake because, if it is active it covers the Volbur with white spots.
Two nf loci however, only turn the back white.

Omit with mutation
The white spots ONLY appear on a Natural State Volbur! If a Volbur has a different or multiple mutation/s active they do not have white spots. Only the white back is visible if they have nfnf or turns invisible nn.

Omitt with Melanism
Melanism means the Volbur mutates with Natural state, traditionally (b&w) with more than 2 mutations active. What happens if multiple mutations are active on a Volbur but the Natural state is not fully active?
I am going to show you here what happens.
