If you own an Ambilobe or Ambanja, photograph the lateral bars in even light. File the photo with the date — bars deepen across the first two years.

The blue bar gene — heritable, not guaranteed.

The blue lateral bar in Ambilobe and Ambanja lineages is heritable but expression varies. Pedigree gives probability, not certainty.

The blue bar gene — heritable, not guaranteed.

Bar coloration in panthers is the product of multiple genes interacting with developmental conditions in the first 12–18 months. A pair of strong-bar Ambilobes will produce offspring largely in the blue-bar range, but you should expect variation across a clutch — some animals with intense bars, some with subtler expression, occasionally one that breaks the pattern.

If a breeder guarantees a specific bar intensity at the juvenile stage, treat that as a yellow flag. Honest breeders give you probability ranges based on the pedigree, photographs of parents and grandparents, and a willingness to discuss what the variation might look like.
