Giant

What Giant looks like

Heterozygous at the Giant locus (Gg). Noticeably larger than normal leopard geckos when fully grown. Adult weight typically 80-110g vs 40-55g for normals. Proportionally larger in all dimensions. Longer and more robust, not just heavier. Cannot be reliably identified as hatchlings; size difference becomes apparent during growth. Color and pattern are unaffected by the Giant gene. Discovered by Ron Tremper.

The Giant locus is an incomplete dominant trait that increases overall body size. Three phenotypes based on zygosity: Normal (no Giant gene) reaches typical adult size of 40-55g. Heterozygous Giant (Gg) reaches 80-110g and is noticeably larger than normal. Homozygous Super Giant (GG) reaches 110-170g+ and can exceed 11-12 inches in total length. Dramatically larger than normal leopard geckos. The Giant gene affects growth rate and ultimate adult size but does not alter color or pattern. Giants and Super Giants require somewhat more food and larger enclosures than normal leopard geckos. The Super Giant form is particularly impressive and commands premium prices.

How to identify it: Giant (Gg): Noticeably larger than normal leopard geckos when fully grown. Adult weight typically 80-110g vs 40-55g for normals. Proportionally larger in all dimensions. Not just fatter, but longer and more robust. Cannot be reliably identified as hatchlings; size difference becomes apparent during growth. Super Giant (GG): Dramatically oversized, reaching 110-170g+ as adults. Can exceed 11-12 inches total length. Visually striking due to sheer size. Must be fed appropriately to reach genetic potential. Size is the ONLY phenotypic effect. Color and pattern are unaffected by the Giant gene.

How Giant is inherited

Giant follows a incomplete dominant inheritance pattern, carried on the Giant allele (locus Giant).

Combo morphs with Giant

• Giant RAPTOR

  Combination of Giant (incomplete dominant) with RAPTOR (Tremper Albino + Eclipse). A larger-than-normal gecko with the RAPTOR phenotype of solid red eyes and orange body. The Giant gene adds impressive size without altering the RAPTOR color and pattern. Super Giant RAPTOR (homozygous Giant) is even more dramatic in size.
