Leopard Geckos, like most other reptiles, have different morphs, which are variations in their color, pattern and size.This is determined by their genetic inheritance. A lot of the time, breeders will make very interesting looking, but expensive morphs. It is important to look into breeders before buying from them. This makes sure that they are treating their geckos well and that they have a long life span ahead of them. Morphs are not really important for anything aside from looks. Most Leopard Geckos are going to be yellow with blackish brown spots as the pattern on their whole body. These will be the cheapest geckos you will find, as they are not unusual or rare. The most expensive geckos will be different colors, like solid black, or black and white, albino geckos, orange, or even just cool patterns on their skin. They can also have different eye colors and can be larger or smaller than the average gecko.
