Question about temp sexing

[justindh1]

I know that Mack Snows are a not like other genetics in being able to temperature sex during incubation but I have a question about the topic. My questions is does this always apply no matter what when the Mack Snow gene is present even if there are several others involved too? An example would be Mack Raptor or Stealth. I haven't noticed anything but wanted to get others opinions as well. It is just something I have been thinking about lately and wonder if there was any test done with multiple genetics when they were first introduced. I also wonder what causes the Mack Snow genetically to be the freak out of the bunch? If anyone could shine some light on this I would appreciate it.

That's a great question which got me thinking, would love to see the replies

I've not heard anything before about not being able to temp sex Mack Snows. I would like to know where you got that information. I'm not saying you are wrong by any means. I am just curious, and would like to read up on it more myself. We have always treated those eggs the same as all the others, and didn't have any significant differences. The last couple years we have incubated everything at 82F. Mostly girls with only a couple boys every once in awhile. Those boys were multiple morphs, not just snows.

I've heard of mack snows not being temp sex dependant, but to my knowledge, most people haven't seen much truth to it. There's already a few threads on this topic, i'll search for some and edit them in.

Thanks for those! I have ready many others and they all seem to have contradicting info on whether mack snows can be temp sexed. I haven't had any luck with temp sexing them at all. Maybe it's just my bad luck but not sure now. I wonder if we can get anyone to chime in thats worked with them for quite a while?

So I guess with the lack of responses that no body is sure of whats going on!

My Macks and E. fasciolatus are not consistently temperature sexable. Never have been.

I've been breeding Mack snows, including a snow E. fasciolatus cross female for the past 3 years incubating at 82 or so and have produced about 1 male a year, so in my experience, they have been as easy to temp sex as my non-snow geckos. I wonder if there's any difference in reliability based on the temp range: for example, is incubation at 88 (for male) any more or less reliable than incubation at 82 (for female)?

Thanks Marcia and Aliza! I haven't had any luck period temp sexing mack snow whether or not any other genetics are involved or not. Just was curious about others opinions.

I would also be curious to see if anyone noticed a difference in temp sexing at the male temps vs female temps. This make me more curious of the variables that affect the TSD of Macks. I hatch a low number of geckos so I typically incubate at 85 to get both sexes. Most of my Macks turn out to be males when incubated at that temp.

We'll have to let you know what we get this year. We are incubating a few clutches for males at 88 and the rest for females at 82. I'm glad I ran across this thread. It may answer some questions before I even have them. We'll just have to see what pops out of the eggs.
