Labyrinth Boa Constrictors
The markings of a Labyrinth boa join together into one maze-like pattern along the body, meaning it loses the separate saddles of a normal boa. The Crystal is the super form and looks nothing like it as a white boa with blue eyes.
About the Labyrinth gene
The Labyrinth is a pattern gene found in the boa constrictor. One copy is enough to show it as it blends the markings together into a maze along the body and breaks up the saddles a normal boa carries. A Crystal is a white boa with blue eyes and is produced by two copies.
Appearance
A normal boa has a row of blocks for saddles down its back. These break apart and rejoin into a complex lateral pattern on a Labyrinth, making the body look like one connected maze. This pattern is crisper and cleaner than the one on a normal. You can pick a Labyrinth out by eye because one copy changes the look plainly enough. The Crystal is the super form. It looks nothing like that. It is a blue-eyed boa with the look of a leucistic.
Genetics
Labyrinth is incomplete dominant, which the hobby loosely calls "co-dom". A single copy gives a Labyrinth while two copies give the super form, Super Labyrinth, known in the hobby as Crystal. There is no hidden het to buy because a single copy shows. Several breeders offer Hypo Labyrinth, which is an established combination.
