Fringing Crested Geckos
A strip of cream to white runs along the back of the hind legs of a fringed crested gecko and sometimes reaches down to the feet. This appears on almost any base colour. The amount of the leg covered varies from one gecko to the next.
About the Fringing gene
A fringed gecko features extra highlighting along the leg instead of a change to the pattern or colour of the body. This cream to white colouring along the back of a crested gecko's hind legs is called fringing. It often reaches down to the feet and kneecap. Most crested geckos carry some degree of it. This shows up on patternless animals and geckos of almost any base colour or pattern.
Appearance
This mark often begins by the kneecap or tail base and goes down the back of the hind legs to the feet. This mark is usually white or cream but can be yellow or orange. Because tangerine tints the whole animal, a gecko that is also tangerine will have that colour. It is one of the small individual markings that show up on a patternless gecko rather than a named morph of its own, like knee caps and portholes.
Genetics
Because Fringing has no confirmed dominant, recessive or incomplete dominant mode, its inheritance is left unstated on this page. The trait is counted as an individual characteristic instead of a single, countable gene. It is closely tied to Whiteout/Whitewall and to WP (white pigment), and it appears whenever an animal carries WP. By pairing a fringed animal with one that shows none, you can add it to a line in a single generation. It is listed as both Fringing and Pos Fringing.
