What Black Eyed Leucistic looks like

Homozygous or compound het at Fire complex locus. Pure white or near-white with solid black eyes. Super form of Fire, Flame, Vanilla, Sulfur, etc.

Multi-allele locus producing brightening/whitening effects. Heterozygous Fire produces a lighter, brighter animal with enhanced yellows and slight overall brightening. Homozygous Fire produces a Black Eyed Leucistic (all-white animal with black eyes). Multiple alleles reported at this locus: Fire, Flame, Vanilla, Sulfur, and Disco, though some may represent the same allele from different lineages rather than truly distinct alleles. Any two alleles from this complex bred together produce a Black Eyed Leucistic super form.

How to identify it: Fire (het): subtle brightening, lighter overall, enhanced yellows, slightly faded pattern. Super Fire / Black Eyed Lucy: completely white or near-white with solid black eyes. Fire is one of the subtler morphs as a single gene.

How Black Eyed Leucistic is inherited

Black Eyed Leucistic follows a incomplete dominant inheritance pattern, carried on the Fire Complex allele (locus Fire).
