Pale yellow snows

[telliott4]

So I have been hatching a lot of these pale yellow snows (or so I think they are snows) instead of black and white. These two are clutch mates and were sired by a super snow so I am pretty sure all the others that are pale yellow are indeed snows. Those that have bred snows have you seen this before?

Yes, it seems like this effect is one of the "most common and yet unrecognized" versions of Mack Snow:

Yes, and it drives me crazy. I've had pairings where I had to sell the offspring as "possible Mack snow" because I really couldn't tell at all if they were snow or not because of the yellow. That was a helpful link.

I produced some dessert snows last season pure afghan x Mack snow and all the snows had that look. This year I produced two jet Black with bright white I curious to see the difference later on

Thanks, that was very helpful.

So after some thought I have found myself on this thought: If mack pastel is dominant while mack snow is incomplete dominant, how then does my super snow x normal produce these hatchlings?

Aliza: Have you ever held back any of these to see what their progeny look like?

The original female that produced these possible pastels was (and remains) a snow blizzard that was paired to my Tremper albino. It was very hard to tell whether or not the babies were Mack snow. I held back one of her babies that I thought was a Mack snow and, when bred back to that Tremper father, she produced a few geckos that seemed to be snow albino. It was very hard to tell about her offspring as well. Last season I paired her with my hypo Mack snow male, hoping to get super snows with speckles (due to her being het for blizzard). Of the 21 babies that hatched, about half were snows and none were super snows (to add insult to injury, the same male was paired with a new female that I didn't know was a snow and produced several super snows including a total eclipse). I have no idea whether I just didn't hit the odds on super snow (with 21 babies, that doesn't seem likely), whether the female is a snow, but not a Mack snow, or whether she's not a snow at all and I was wrong about the tramper snows the previous season.

Mack Pastels are dominant in that they do not produce a super form (Pastel x Pastel does not make Super Snow). I would guess that your Super Snow, instead of being genetically Mack Snow / Mack Snow is actually Mack Snow / Mack Pastel. If that were true, you would get some Mack Snows and some Mack Pastels from your Super Snow x Normal pairing.

I don't know of any specific test breeding done for Mack Snow x Mack Pastel, but it makes sense that a gecko with both would have the appearance of a Super Snow.

 

[acpart]

well, that would explain why I didn't get any supers from my Mack (?pastel) x mack snow pairing.

I don't know, Aliza, thinking about the "odd" hatchling you had, I wonder if that one is a Super now, but it's a Mack Snow / Mack Pastel Super, which makes it look different? There are still some really mysterious things about all the Mack Snow genes...

I don't think the non-snow parent was a Mack pastel and the snow parent certainly wasn't (he's produced super snows).
