Mack Snow Origin

The Mack Snows came from John and Amy Mack from Reptiles by Mack. They came across some hatchlings which looked like "Snow" hatchlings rather than normal hatchlings. The following season, John and Amy bred the hatchlings back to each other. In the breeding, they produced Super Snows, Mack Snows, and Normals.

Mack Snow Classification

There are a few distinct features of Mack Snows which normal Leopard Geckos do not express. As hatchlings, they have white bands instead of yellow bands. See the pictures below for comparison. Most Mack Snows will tend to lose their white as it will fade to yellow as they grow older.

Another key feature of Mack Snows that while all the other Leopard Gecko morphs are temperature sexed, Mack Snow Leopard Geckos have not been proven to be consistently temperature sexed. Normally, temperature sexing works in the following way: 80°F - 83°F majority females will be produced, 84°F - 86°F, an even mix of males and females will be produced, and 87°F - 89°F majority males will be produced.

Mack Snows, when bred to Mack Snows, have the ability to produce a Super Snow. The genetics of Super Snows will be discussed in the next section. When they hatch, they seem to have an all purple or silver hue to them. As they grow, the birth color fades into a white body with black broken pin stripes. They also have two solid black eyes.

Mack Snow Genetics

Mack Snows were first to be thought as Co-Dominant. Now after further review, they seem to be Incomplete Dominant. There are three different forms, Super Snows, Mack Snows, and Wild Type. The Super Snows are the homozygous form of the Mack Snow gene. The Mack Snows are the heterozygous form of the Mack Snow gene. The Wild Type do not have the Mack Snow gene and generally look like Normal Leopard Geckos. See the pictures below for examples.

There are different results when breeding Mack Snows. Listed below are different possible combinations.

Mack Snow Crosses

Currently many different breeders are working with Mack Snows, crossing them into different morphs and creating new and exciting combinations. For example, Alberto Cadolini from A&M Geckos and Ron Tremper have crossed Mack Snows with R.A.P.T.O.R.'s creating what Ron calls a Super R.A.P.T.O.R. A Super R.A.P.T.O.R. is an all white Leopard Gecko with Red Eyes.

Albey from Albey's "Too Cool" Reptiles has sought to strengthen the Mack Snow line by breeding his Line Bred / Fasciolatus females into his Mack Snows. From this, he has produced Mack Snow / Fasciolatus. When comparing one of his Mack Snow / Fasciolatus to a normal Mack Snow hatchling, the Fasciolatus have longer tails and are bigger as hatchlings.

Kelli Hammack from Hiss has crossed Mack Snows with the new morph developed by Mark Bell, the Enigma. She has also bred her Mack Snow Enigmas, into her Bell Albinos, creating Red Eye Mack Snow Enigmas.

Paul Sage from Paul Sage Reptiles has crossed his Mack Snows with the Murphy Patternless morph and with Rainwater Albinos. As hatchlings, the Mack Snow Patternless' look like normal Patternless', but express lots of white pigment instead of yellow. As they grow older, they show more white than a normal Murphy Patternless.

Pat Kline from Luxurious Leopards is working on crossing Mack Snows with Bell Albinos and Blizzards. Currently he has produced Super Snow Bells and Super Snow Blizzards. The Super Snow Bells look like Super Snows, but do not produce black pigment. They have all red eyes and a white body with pinkish stripes. The Super Snow Blizzards look like Blizzards that have a white frost to them. They also have solid black eyes.
