A gecko showing Patternless — Harlequin with Patternless (two copies)

What it looks like

Patternless is recessive. With two copies there is no pattern on the dorsal, the side or the legs. It is different from Phantom, which blends colour but can keep pattern.

This page shows Patternless drawn from its genes. For the written reference, inheritance tables and breeder notes, see the crested gecko morph guide on ReptiDex.

In depth

Complete removal of pattern elements. Distinct from Phantom (which is a melanin-producing trait); Patternless removes pattern structure entirely. Homozygous animals are completely unicolor with no pattern lines, spots, or flames.

How to spot it

Patternless animals are solid/unicolor with no visible pattern elements. Distinct from Phantom, which retains some pattern but modifies melanin.

Where it came from

Patternless was initially confused with some Phantom phenotypes but is genetically distinct.

How it is inherited

Recessive: it takes two copies to show.

Written as PTL+ and ptl

Patternless is a true structural pattern removal, not a color modification. Recessive inheritance confirmed. Source: Foundation Genetics Part 1.
