Breeding Notes
- Super Salmon is the homozygous form of the Salmon gene
- All offspring will be 100% heterozygous for Anery
- 50% chance of Hypo in visual offspring

Boa Constrictor Genetics Guide
Inheritance Patterns
Recessive
Requires two copies of the gene to be visible. Examples: Albino, Anery
Co-dominant
Shows intermediate form with one copy, super form with two. Examples: Salmon, Hypo
Dominant
Visible with just one copy of the gene. Examples: Jungle
Breeding Terminology
Visual
An animal that shows the physical traits of a morph.
Het (Heterozygous)
Carries one copy of a recessive gene but doesn’t show it visually.
Super Form
The homozygous form of a co-dominant gene.
