Wouldn't you know it, the email won't stop...and "we've" got a big show Sunday. This post is a follow up to an earlier post started by Sam of ReptileKings:

A good number of you are asking and gathering info on Line Bred Snows vs. the Mack Co-dom genetic Snows. I'll try to summarize it in a nutshell.
The Mack Snows are expensive.:D Nothing like cutting to the chase. Here are some "finer" points...

The line bred Snows are beautiful. Sam has some fine examples and currently has hatchlings for sale :) When working with line bred leo's.. and I can quickly think of 3 separate lines... it's always best if you start with a 1.1 . Not going to go to far with just a single male or female... you need to chase that coloration from both sides. Got it? Email Sam for his reservation list.

The Mack genetic Snows have a co-dom gene. This means that gene will transmit itself 50% of the time to the hatchling... and it doesn't matter what morph the other parent is. Now... pay attention here. The Mack Snow will yellow. Got it? OK, it will yellow to varying degrees... with the Hypotang Snows being top of the list... but some degree of coloration is guaranteed. Chances are real good you are not going to impress anyone with your genetic Snow. So, why purchase one then? Because, when you cross the Snow x Snow gene... you get this

And that leo stays black and white forever. A little too much flash in that photo...drop by Sunday and see her yourself.

You cannot tell them apart. Price and breeder reputation are real good indicators. Here's my latest addition below... compare her with Sam's hatchling on the gold background...you'll see the problem!

I know the 'first generation' Mack snows, being het for co-dom snow turn somewhat yellow, and the line bred snows come in various degrees of yellowing.
Both lines will yellow to some degree. There is no such thing as "het" in either the line breds or the Macks. The gene is co-dom, no het for Snow exists. You either are a Mack Snow...or you are not. If you are a line bred Snow, keep holding back your very best hatchlings,and rebreeding them. Outcrossing becomes a necessity.

So, if I wanted to be sure I was getting a Mack snow or super snow, I'd have to make sure they were past the hatching stage or I could be fooled, right?
Exactly..... wrong. As the Mack ages...it could present as a normal leopard gecko. If you are the nervous type, ;) I'd be asking to see hatchling pics, asking re breeder reputation, and asking for a contact person from which the line is descended... in my case Alex Hue in Michigan.
The SuperSnow is unmistakable in presentation. I doubt many people would need help with that one!:D

Now, I’m off to get ready for Show Time:D Those of you with more questions can see me at the show

Okay, that makes sense. Get any 'brand' of snow a.s.a.p. while they're still showing white and black bands. And above all, make sure you can trust the breeder not to pull the wool over your eyes if you're getting an older (yellowing) snow.

Thanks Linda. :)

I'm just curious about the history of the Snows. I believe the line breed Snows, or at least the Urban Gecko Snows were from wild caught geckos.
Any idea of where the Mack Snows started out from?
Great thread too:)

The Mack Snow is the result of a mutation/evolution that most likely took place within the colonies of John and Amy Mack's (Reptiles by Mack) collection. Its a mutation that evolved and showed up in their collection over time.

You could compare the Mack Snows showing up in their collection very much like the natural evolution/mutating in the wild. The Mack Snow is not a morphthat was found and collected in the wild, and then purchased by a collector abroad.

Simply, it s a morph that has taken form and shape naturally within a captive environment. No specific matching of leopards or breeding for this trait occurred. Evolution with a ring side seat, if you will.

Humans can get their egos up doing a good deal with line breeding... but lets not start thinking "we" can create genes.
