Breeding Pair Compatibility Checker

Q: What is the minimum breeding weight for female ball pythons?

The commonly recommended minimum breeding weight for female ball pythons is 1,500 grams, though many experienced breeders prefer 1,800 grams or more. Breeding underweight females can lead to health complications, smaller clutches, and poor recovery.

Q: Are there lethal gene combinations in ball pythons?

Yes. The most well-known is the Spider x Spider pairing (super spider), which produces offspring with severe neurological issues. Other combinations to research include certain Desert and Champagne pairings. Always research your specific morph combinations before pairing.

Q: How old should ball pythons be before breeding?

Males can begin breeding at 600+ grams and around 12-18 months old. Females should be at least 2-3 years old and meet the minimum weight requirement. Age is less important than weight and overall condition.

Q: Can I breed related ball pythons?

While linebreeding (breeding related animals) is practiced in the reptile hobby, excessive inbreeding can lead to reduced fertility, smaller clutches, and health issues. Track your lineage carefully and avoid pairing direct siblings or parent-offspring pairs.

The Breeding Pair Compatibility Checker evaluates whether two animals are suitable for pairing. Enter each animal's morph genetics, weight, age, and health status. The tool checks for known lethal gene combinations, size compatibility, minimum breeding age and weight thresholds, and genetic diversity to help you make informed pairing decisions.

Disclaimer: This tool checks for common compatibility issues but cannot evaluate all possible genetic interactions. Always research specific morph combinations and consult experienced breeders. Animal welfare should be the primary consideration in all breeding decisions.
