Fire Boa Constrictors
A single copy of Fire gives a visually distinct boa constrictor, and two copies give Super Fire, a fully white, patternless snake with black eyes. Past that, the single-copy look is barely documented, so judge one from photos of the animal itself.
About the Fire gene
The Fire gene in boa constrictors produces two different looks. A single copy creates a visually distinct animal, while two copies result in Super Fire, which is patternless and fully white. This gene was brought into captive breeding by Jeremy Stone. It has spread into collections worldwide since then. Keepers prize it above all for the way Super Fire looks so striking.
Appearance
The two-copy form, Super Fire, has black eyes and is patternless and fully white, with very little pigment reaching its scales. While a single-copy Fire is a visually distinct boa constrictor in its own right, its look beyond that is not documented in detail.
Genetics
Fire is incomplete dominant. A single copy produces a visually distinct animal, while two copies result in Super Fire. This morph is known as Princess Diamond in females and Emperor Diamond in males by the hobby. No known complex contains Fire. It has no documented allelic partners or established combo lines. Stone's hets in Italy produced the first captive-bred Super Fire.
