Tiger

Dark bands down the side, with the pattern pushed into the gaps.

Shows on the upper side and the middle of the side.Dominant: one copy shows.

What it looks like

Every crested gecko carries Tiger. It pushes other pattern around, and that is what turns flame and harlequin into vertical bands.

Geckos described as Tiger show the tigering itself: dark bands of base colour from the base of the pins down through the upper and middle side, with the pattern pushed into the gaps. Brindle is broken tiger: finer bands, broken into pieces.

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

Brindle is broken tiger
On a Brindlequin (Yellow, White Pattern, Harlequin, Pinstripe and a visible Tiger) the bands break into pieces.

In depth

Fixed dominant trait present in ALL crested geckos; it cannot be isolated from the species. Controls pattern separation and distribution into distinct spots/flames. Similar to spots on leopard geckos or alien heads on ball pythons. Ratio of Tiger to other pattern traits determines expression from brindle to reverse pin to solid.

How to spot it

All crested geckos carry Tiger. Visual identification relies on interaction ratios with Pinstripe and other pattern traits.

Where it came from

Tiger presence in all animals was initially unrecognized because it cannot be separated from the species.

How it is inherited

Dominant: one copy shows.

Written as TIG+ and tig

Tiger is universally present. No known wild-type (non-Tiger) crested gecko exists. Pattern distribution determined by Tiger interaction with Pinstripe and Harlequin. Source: Foundation Genetics Part 1.

Tiger and Pinstripe ratio determines pattern phenotypes including brindle and reverse pin. Ratio-dependent expression.
