Mack Snow, Gem Snow, Tug Snow Leopard Gecko Morph 101

Mack Snow, Gem Snow, Tug Snow Leopard Gecko Morph 101

There are a lot of people who’re owning and working on Mack Snow projects. But surprisingly enough, many of them still don’t know what happens when they pair a Mack Snow with a Mack Snow or a Super Snow. 

If you’ve been thinking of getting a Mack Snow — or you already own one but want to know more about it — this post is going to be a must-read for you. 

Here’s everything you need to know about Mack Snow leopard geckos. 


History of Mack Snow Leopard Geckos

As you’re probably aware, morphs are usually named after the person who finds them. In the same way, Mack Snow was named after John and Amy Mack. 

While the exact date of this morph’s discovery isn’t accurately known, it’s said to be somewhere around 2000-2004. However, according to our research, the final version of this morph was put out in 2004. 


Genetic Traits 

Mack Snow is an incomplete dominant. However, the cool thing about it is that you can pair a Mack Snow with Mack Snow to produce a Super Snow. 

That’s one of the major reasons people love Mack Snows, as they give you the flexibility to have an incomplete dominant, and also produce a super form out of them when needed. 

Furthermore, if you pair a Mack Snow with a Super Snow, you can create something that’s 50% Mack Snow and 50% Super Snow. 



While Mack Snow leopard geckos have regular leopard-gecko eyes, Super Snow geckos have black-colored eyes. It’s one of the major visual characteristics that set them apart. Their entire eyeball is solid black in color with no visual lines. 

Another visual property is their high-contrast body. That means they have a light-colored body with dark patterns on top, which look really prominent. Some of them do have a stripe pattern, while some don’t. 

When a Mack Snow hatches, it has a white body with black patterns on top. As it grows, it develops a slight tint of yellow. 

On the other hand, Super Snows don’t have yellow coloring at all. They’re mostly white with black dots on top. 

If you combine Super Snow genetics with an Albino, the black, contrasty patterns turn to less-contrasty, brown patterns. That’s one of the best ways to tell whether the morph you have is resulting from a Snow and an Albino. 


Final Thoughts

The last piece of advice we’d like to give you: never ever mix a Mack with a Tug or a Gem. If you do, it’s going to be almost impossible to tell them apart, which would ruin your project. Furthermore, Tug and Gem don’t have a super form at all, which makes the outcome even more confusing if you mix them up.  

That being said, now you know everything you needed to know about Mack Snow leopard geckos.
