In Reply to: Egg Incubation and Sex Determination posted by Maxx MacLeod on March 12, 2003 at 02:45:03:

:Steve-- Most turtle species have temperature determined sex ratios. There are some species, however, where sex is determined chromosomally like happens in mammals. I've found that most BIG turtle farmers have egg rooms where the eggs are either kept on racks or they're in a medium, like vermiculite and stacked up somewhere. So what happens is that (similar to what happens in the wild) there are temperature variations throughout time and also, different eggs are at different average temperatures depending on their location in the room, on the shelf, in the box, or whatever. So they get a mix of sexes. But many of the small operation breeders (like me) will incubate specifically warm (for females) or specifically cool (for males). Usually, there's a 10 degree range or so where you get a mix of both. FYI, all Common and Alligator Snappers have temperature determined sex ratios. These species are pretty thoroughly studied and they have a good handle on what temperatures create what sexes. I hope that helps. --Maxx
