Breeding Pair Compatibility Checker Guide

The Breeding Pair Compatibility Checker evaluates whether two animals are suitable for pairing by checking genetics, size, age, and known issues.


What it checks:

  • Known lethal gene combinations (e.g., Spider x Spider in ball pythons)
  • Wobble-producing gene combinations
  • Minimum breeding weight thresholds
  • Minimum breeding age requirements
  • Inbreeding risk if lineage data is provided

  • Lethal combinations to avoid (ball pythons):

  • Spider x Spider (super spider — severe neurological issues)
  • Champagne x Champagne
  • Woma x Woma
  • Pearl x Pearl

  • Wobble/neurological genes:

  • Spider, Champagne, Woma, Hidden Gene Woma, Powerball
  • These morphs can produce animals with head wobble — research carefully before breeding

  • Breeding minimums (ball pythons):

  • Females: 1,500g minimum (1,800g+ recommended), 2-3 years old
  • Males: 600g+ minimum, 12-18 months old
