Western Hognose morph calculator
Choose the genes each parent carries and see the full clutch odds — per gene and per combination. Covers 6 curated western hognose genes, with the allelic, lethal and sex-linked cases handled properly.
Sire (male)
Which genes the father carries, and in what form.
No genes yet — this parent is treated as a normal animal.
Dam (female)
Which genes the mother carries. Sex matters only for sex-linked genes.
No genes yet — this parent is treated as a normal animal.
Add at least one gene to a parent to see the predicted offspring.

Common questions
Is the western hognose morph calculator free?
Yes. No account, no sign-up, and no limit on how many pairings you try. Everything runs in your browser and nothing is stored.
What is a Superconda western hognose?
A Superconda is a western hognose with two copies of the Anaconda gene. Anaconda is co-dominant: one copy reduces the pattern, two copies produce the much cleaner Superconda. Breeding two Anacondas together gives roughly 25% Supercondas.
