I still believe it is dominant in some capacity. But it isn't as simple as "Breed a Green Blotched to a normal and get 100% Halo babies."

Here's an overview so far, after reviewing I am hoping someone can give their thoughts (keep in mind all of these are snows):
Halo x Normal = mix of Halos and Normals
Halo x Green Blotched = 100% either Halo or GB
Halo x Halo = Halos, GB, and normals
GB x Normal = Halos & GB [referencing the 2020 babies]
GB x GB = ?? (I have personally not done this breeding... hard to find a GB male...??)
Normal who produced Halos with a halo or GB x same = Normals. [i.e. not a recessive mutation]

I wonder if it's sex-linked somehow, perhaps Dominant in females but Incomplete-Dominant in males? I look forward to everyone's thoughts.
