A Jungle Leopard Gecko is a Leopard Gecko whose body and tail pattern are irregular. The body pattern will have broken or incomplete bands; the tail will not be banded, and will feature broken or absent bands. 
Jungle x jungle seems produce mostly but not 100% jungles. On rare occasions a jungle is produced by non-jungle parents. In other words, it’s complicated and probably governed by multiple genes. 
The Jungle Morph was developed in 1991 by Ron Tremper. The Jungle Morph is thought to be both Poly Genetic and Recessive. In the case of a gecko that possesses the Jungle trait genetically, but does not exhibit it, it’s likely that the trait will only be passed to the first generation. 
The Jungle Leopard Gecko has a unique patterning per individual on its back that helps means will very rarely find two that look exactly the same.
The tail of the Jungle Leopard Gecko will display broken or absent bands.
Throughout the years many people have thought of the Jungle trait as Line Bred/ Poly Genetic, but recent developments have proven this is not necessarily the case. Many people buy so called Heterozygous Jungle specimens but fail to ever produce Jungle animals. Consequently, some people consider it to be an Incomplete Recessive which means that the Jungle morph works like a recessive trait most of the time but can vary and act as a line bred trait. 
Breeding jungle leopards presents a special challenge. Which exact traits create the jungle morph is not known exactly. It isn’t known whether they are recessive or dominant traits.
Many jungle leos don’t show any jungle patterning at all. Then, their hatchlings will show the tell-tale signs of the morph. Often, hatchlings won’t appear to be jungles until they reach full growth.
This is why jungles are so rare and special. Breeding them is a challenge.
