Any help here appreciated

I just finished probing a litter of six SF rosies. At 46 years old I can't see quite well enough up close to count the small scutes but guess that each probed around ten scales deep.
My female is in shed phase and I didn't want to disturb her so my questions are:

What are the probe depths for Mid-Baja rosies?

Are there any other characteristics, tail length width and spur size you look for? These characteristics are nearly identical in my proven pair but I don't want to make a judgment on two animals

And last, as I'm thinking these are all males, is their any evidence that environmental factors like temps affect the sex of offspring?

Thanks in advance for any insights.
