Kneecaps Crested Geckos
A crested gecko may have a patch of off-white to cream on the front of its hind legs called Kneecaps. This can be a thin line at the knee or a pale pattern that runs down toward the toes. This feature often turns up with fringing on the same legs, and most crested geckos show some of it.
About the Kneecaps gene
A patch of cream or off-white over the knee that stands out from the base colour is what makes up a kneecap. This marking is found on the hind legs of a crested gecko. Since most crested geckos show it to some degree, it is usually just one detail in a gecko's description instead of the whole of it.
Appearance
The cream colour is found on the front of the back legs. While the white pattern goes down the leg towards the toes on some animals, it is only a thin line at the knee on others. For the cream to count as Kneecaps, it must look like a different colour from the base around it. Because Fringing, which is the cream edge along the back of the hind legs, often runs into the knees, these two traits frequently appear on the same animal.
Genetics
Because Kneecaps is polygenic instead of a single gene, there is no super form to look for. It is listed as Kneecaps and as Pos Kneecaps. No first year or originator is recorded for it.
