Explore Genetics Tools

ReptiDex connects morph references, structured animal genetics, and a pairing calculator. A morph guide explains known traits. An animal's allele record stores what you know about that specific animal. The calculator predicts possible offspring from selected inputs.

The current genetics library covers Axolotl, Ball Python, Bearded Dragon, Boa Constrictor, Corn Snake, Crested Gecko, Hognose Snake, and Leopard Gecko. Open Morph Guides to browse the alleles, named morphs, and combinations for one of these species. The species catalog for animal care is broader than the genetics library, so an animal can have a ReptiDex record without an allele guide or calculator. Genetics data can grow over time; check the live species list if you do not see a tool for a species.

Open a supported animal's profile and select Genetics. Choose Add Allele, search for the allele, then set the offered zygosity and your confidence level. Add a note when lineage, a test, or an uncertain visual trait needs context. Save it, then review the animal's computed phenotype. You can edit or remove a recorded allele if better evidence arrives. The available zygosity choices depend on the allele's inheritance pattern; do not force a value just because a morph name sounds similar. Check the species and any risk notes in the guide before using a recorded allele in a breeding plan.

Open Calculator, choose one of the supported species, and use the From collection selectors to choose a sire and dam from your actual animals. The calculator loads each selected animal's recorded alleles into the corresponding parent side. Review both sides before calculating, because unrecorded alleles are treated as normal and an incorrect or unconfirmed record changes the result. In the iOS app, open Breeding, tap Predict Pairing, and choose a sire and a dam the same way. You can also enter or adjust alleles manually to explore a hypothetical pairing. Read the predicted probabilities as possible outcomes, not a guarantee of any particular hatchling. If the pairing is useful, use the save-pairing action where offered and keep actual clutch and offspring records separate from the prediction.

When a pairing can produce a lethal combination, the calculator shows a warning with the share of predicted outcomes that are lethal and marks those outcomes in the results. In crested geckos, for example, two Lilly White parents can produce Super Lilly White, which is lethal. The warning appears on every plan, on the web and in the iOS app. Some combinations also carry a health note: Super Cappuccino in crested geckos is one. The web calculator shows that note beside the outcome. Treat a warning as a reason to rethink the pairing before it happens, check the trait in Morph Guides, and confirm each parent's recorded alleles, because an unrecorded allele is treated as normal and can hide a risk.
