Mack snow incubation temps

[trizzypballr]

I know that temp sexing mack snows isnt accurate, but is it partially accurate, or it means nothing at all? For instance, if you incubate all the eggs at 89 degrees so they hatch fast, will most of them be males since it was the male temp, or is it a total grab bag? theoriticly 50% each? When you breed a co dom to a normal, for instance lets say were breeding a co dom het blizzard to a blizzard, oviously some of the offspring will be normal blizzards, some will be het blizzards, i know the co doms arnt temp sexable, but the blizzards and het blizzards will be correct? so giving the same circumstance that everything is incubated at 89 degrees anything that isnt a co dom its safe to say is a male?

since no one has answered yet...and mind you im not 100% sure, only about 95% sure. im sure if im wrong someone will correct me. but i do beleave they can be sex temped just as normals can be. again...from what i understand, its just that the codom males take longer for the buldges to become visable then normal males. and thats what i think the reason for them saying that its not accurate. again, anyone can chime in and tell me im wrong. hopefully im not.

I have witnessed this, but also have got both sexes from both temperatures.

It doesnt make alot of sense to me for the siblings to sex OK, and just the Macks be a little off, but that seems to be what is going on. Anyone have more info on the sexes of their TSD Mack Snow siblings?

To chime in kind of on my own question From what I understand the whole term Sibling actully means nothing. Its either a normal, a co dom, or a super snow, Sibling is just a way of saying that It came out of a Mack Snow project but doesnt carry the genes. So the Siblings being temerature sexable would make sence to me. Taking the co dom het bliz crossed to a normal blizz example again. 50% of the offspring will be co dominate mack snows, the other half with be non mack snows. The mack snow gene is the gene that is messing with the temp sexability. Ive heard rumors before that some people beleive that the mack snow was actully made by crossing a leopard gecko to a close relative, starts with fac something I forget the name, but it was also noted that they are not temperature sexable either, which makes even more sence then if it is true. The real question I was getting to, now that I think about it, in my pairing mentioned earlier, all of the non macks i would want to be females, so i would incubate all the eggs at 82 degrees, my question is from everyone elses experiences, are MOST of my mack snow hatchlings going to be females because of the incubation tempature, or is its truely going to be random no matter the temp. Is it just that the temp sexing in mack snows isnt always accurate, or is it non existant?

By sibling I only meant whatever is not a Mack Snow.

Well if it did have something to do with subspecies intergrade, ALL of the babies are a mix of whatever those are, no matter what color they are, thats why I think that sounds really weird. I was thinking that sounded like the reason for this. Subspecies might have differences like that, from living in different areas, etc. I have no idea how just a morph would be so different

Its not as if the normal half magically does not have the blood of both parents, or two subspecies or whatever, is what I mean. If the non-TSD were a random mix between all of the geckos hatched I could see it, not if the "trait" is picking which color it likes better. I am no scientist though.

From what I understand 78-79 degrees 90% females - 89 degrees 90% males.

My first 2 macks at 90 degrees are male. Ill post in a week or two on the other 3

so you guys are saying your macks have mostly been temp sexable?

No, I'm saying that is what I was led to believe, I will let you know when my eggs hatch. I'm sure there are other's around here that can answer that question.

 

[eyelids]

Mine have been, but I only hatched 6 last year. This season I should have more conclusive evidence to offer. The majority of my Mack eggs will be incubated at 82 so hopefully I get lots of females.

No, normal temperatures do not seem to apply.

I dont know what to say, other than both sexes can come from both temps. I really dont know if it means they are temp sexable or not. It may be just random. For the most part it seems opposite, the high temp producing the females, but I did get males from higher, and females from lower temps.
