Portholes Crested Geckos for sale in the UK
A crested gecko's sides feature portholes, which are off-white to cream scales that break out. These are a fixed marking of their own instead of a stage of ordinary white spotting. Because they are not tied to one base pattern, they can turn up on a gecko carrying almost any other trait.

About the Portholes gene
When a crested gecko has off-white to cream scales that are raised and scattered along its sides, the name Portholes is used. This mark is counted as a fixed trait by breeders instead of a stage of ordinary white spotting. Because it is not part of the Tricolour, Snowflake or Dalmatian pattern, it can appear on a gecko with none of those traits or any of them.
Appearance
The scales sit a bit proud of the skin, mostly along the lower laterals but sometimes on the limbs or further up the sides. Size, shape and number vary from animal to animal. Each porthole is a patch of lost pigment over a stripe that runs low on the flank, the same stripe a Lilly White shows fully white. Portholes turn up on many different base patterns instead of being tied to one. Sellers list it as its own trait alongside whatever pattern the gecko already carries.
Genetics
Portholes is a polygenic trait. It is made from several genes working together instead of a single dominant or recessive gene. Because of this, there is no super form on record and no het to look for. It belongs to no allelic complex. The only other name for it is the shorthand Ports. You will see Portholes and Pos Portholes in listings. The second name is used for young stock with scales that are not developed enough to call with confidence. No originator is on record and no first-produced date is on record.
