Egg Temp influence gender?

[Vattica]

Just a thought: Has incuabtion temps ever been known to influence the gender of the offspring? I was flipping through an old, outdated book and the author was mentioning that he incubated some eggs at too low a temp and got all females - coincidence? I have never heard of this happening before, in fact, I thought it did not happen w/ chams...

hey,

incubation temp does not determine sex with chameleons. it ussually either speeds up the process or takes a long time to hatch out your young. i have never seen a clutch or heard of one that only have one sex in it.

Same here - everything I've read says it isn't a factor in sex determination. Higher temps, though, will lower the hatching rate and cause more deformity (high temps = rapid development = deformities). Things like small/stunted/weak hatchlings, crooked spines/tail and short tongues have been reported. Most report hatchlings incubated on the lower end are more robust.

Now, that was the impression I had also, but I have heard of this not being the case-

Have you guys checked out the answers to this on Kingsnake?Fascinating discussion we had going on in there - worth your while, I promise. :)

and I think there may be some pattern affect (non-genetic) with temp manipulation but not sure

In chameleons?? Are you sure? Now that would be fascinating! Suddenly anyone could have morphs w/o paying extra...
