What Mystic looks like

Heterozygous Mystic allele at BEL locus. Dark coloration with subtle purple tones.

Major multi-allele locus. Each heterozygous allele produces a distinct morph with its own visual phenotype. Any combination of two alleles from this complex produces a Blue Eyed Leucistic (BEL): a pure white or near-white animal with vivid blue eyes. Core proven alleles: Lesser (lighter color, reduced pattern), Butter (similar to Lesser, sometimes considered the same allele from a different line), Mojave (dark coloration with distinctive "flaming" pattern and patternless belly), Phantom (dark base, reduced pattern), Mystic (dark with subtle purple tones), Russo (lighter with reduced pattern), Special (lighter base), Bamboo (lighter with reduced pattern). The "Daddy" gene is a more recent addition with less extensive documentation.

How to identify it: Lesser: lighter overall, reduced dark pigment, clean belly. Butter: very similar to Lesser. Mojave: dark chocolate tones, distinctive flaming on sides, patternless white belly, dark crown on head. Phantom: dark base, subtle pattern reduction. BEL (super form of any combo): pure white, blue eyes.

How Mystic is inherited

Mystic follows a incomplete dominant inheritance pattern, carried on the Blue Eyed Leucistic Complex allele (locus BEL).
