Reptile Morph & Gene Library — Inheritance, Zygosities and Descriptions

Example: Ball Pythons (Blue-Eyed Leucistic [BEL] & Black-Eyed Leucistic) The BEL complex includes co-dominant genes like Mojave, Lesser, Butter, Russo, Phantom. If an animal inherits one copy, it has a different morph (e.g., Mojave). If an animal inherits two copies of compatible genes (e.g., Mojave × Mojave), it becomes a super form—a pure white "Blue-Eyed Leucistic" (BEL) or "Black-Eyed Leucistic" (depending on the genes).

Co-Dominant: One copy is visibly expressed. Two copies produce a distinct "super" form, which differs from gene to gene — see the individual gene for what its super looks like.

Member of the BEL complex; produces BEL in supers or with compatible alleles

BEL complex allele interactions can produce leucistics

Co-Dominant: One copy is visibly expressed. Two copies produce a distinct "super" form, which differs from gene to gene — see the individual gene for what its super looks like.
