Few questions

[ltlehman]

can anyone list the "genetic specs" of a mack snow? I'm not sure if I'm asking this correctly because I'm completely new to genetics but like what would the outcome be if i cross a mack snow with an APTOR? I think macks are co-dominant...what would that mean for some breeding projects? what can it not be combined with and what can it be combined with basically. and mack snows can be het for something but something cant be het for mack snow right? sorry bout all the questions

You can cross a mack snow to any leopard gecko on the planet. Mack snow are codominant so in a nut shell mack snow X aptor will give you50% het aptor normals and 50% mack snow het aptors. To get all mack snow animals use a super snow which produces all mack snows when bred to a non mack animal.

You are right that something can't be het for mack snow, since a gecko either has 1 Mack snow gene and expresses it (consistently by being born black and white, but not necessarily as an adult), 2 Mack snow genes and is a super snow, or no mack snow genes and is not born black and white.

You also wanted to know about breeding outcomes. What I mean by the phrase above "but not necessarily as an adult" is something I've seen in pictures on the forum of Mack snows and found out to my disappointment in my first year of mack snow breeding, namely, that many of these animals which have 1 Mack snow gene are indistinguishable from non Mack snows. This seems to be especially true with Mack snow x SHTCT crosses. This season I crossed my super snow male with a SHTCT and with a Mack snow/fasciolatus cross that also had line bred snow lineage. So all their offspring are either Mack snow or super snow. Only a few of my snows maintained any white coloring or pale yellow. Most of them ended up being mustard yellow or tang and nearly all had significantly reduced or non existant spotting, even those from the snow x snow cross. I wonder whether there are genetic features in the super snows that don't express themselves but that can be passed on to non-super snow offspring.
