Temperature sexing for Mack Snows?

[stinky]

Hi guys, need to verify another "interesting" advice.

My local breeder says that all his morph can be sexed using temperature EXCEPT mack snows.

From his experience, there is a 50-50 chance for him to get male Mack Snow even if he put the eggs in lower temperatures for the first 3 weeks.

Is that right?

Ive noticed with mack snows (and i know a lot of breeders i have spoken to about it here in the UK and over your side of the pond have noticed the same) that mack snows are harder to sex using incubation temperatures, and also they take longer to become sexually mature.

Im not sure if 50/50 would be a good way to describe it without facts backing it up, but out of 6 mack snows all incubated between 80-82f 2 hatched male. I have done no more mack breedings since so cant shed any more light on it though./

i would agree with the breeder, snows are a wildcard with temp sexing it can work, but not allways.

temp sexing has worked for me with my mack projects, but i do know this isnt always the case. This is also true for the afganicus.

In 2 years of breeding Mack snows and super snows, incubating for female at 80-82 I have gotten exactly one Mack super snow male.

I have A LOT of snow variation projects and have had a roughly 90% success rate of hatching what I incubated for. So you can say it is not guaranteed but it will be pretty close.

OK ... so, the best thing is just to test for myself and see ... noting that I may not get what I wanted.

Since Mack Snow is late to mature, as stated above, I wonder if incubating the eggs at lower temperature for > 3 weeks will help.

My Mack Snows have all conformed to the general TSD predictions. They have also grown and matured normally, too.

The thing is temp sexing is never 100%... In general most species will always produce more females than males... To be honest even at male temps I have produced many females with mack and non-mack leopard geckos...

Certainly. While I haven't had it happen to me yet, I have had geckos from others that defied the generality.

Additionally, tortoise breeders know all too well how poorly it can predict in Aldabras, Marginateds, and some others. Different animals with a reverse TSD relationship, sure, but the same principles apply. It really sucks to take the hit of buying an animal with (temp induced) split scutes only to have it turn out male anyway.
