It just dawned on me as to a likely explanation for the high rates of deformities seen using Trempers incubation method, as well as the higher rates of deformities seen when incubating eggs at 90*F and above.
When organisms are sujected to stress associated with high temperatures they undergo changes in gene expression. This stress caused by high temps is called heat shock, which leads to a dramatically higher chance of mutation.
The effects of heat shock have been studied for many years in Drosophilia (fruit flies) and is known to lead to deformities. When the fruit flies undergo heat shock one deformity that comes to mind is the growth of an extra set of legs (right on the head where the antennas are supposed to be).
So basically what this means is that heat shock, coupled with a severe rise in incubation temperatures (which we know causes developmental problems) could quite possibly lead to a dramatically higher rate of deformities in leoaprd gecko hatchlings.
If any of you genetics teachers out there have anything to add please do...
Just something to consider.
