Sex ratio in C. cyanurus/chenggongensis

[Jennewt]

I have a group of 6 breeding adults, and have produced large numbers of offspring for several years. The offspring have a skewed sex ratio - mostly females.

My breeders came from two different sources. There is no locality information for either group, so it's possible they are different races/localities/subspecies. Is it possible that this could cause some kind of genetic problem that would favor female offspring?

Has anyone bred enough numbers of C. cyanurus/chenggongensis to have any information on the sex ratio of the offspring? I really wonder what is going on.

I have no personal data to contribute, but these kinds of sex ratio inequalities are very interesting. There are a number of mechanisms that could give raise to the skewed ratio but there´s no telling which one is responsible....

well, for what it's worth; the 4 youngsters I got from Jen turned into 3 preggers females and 1 horny male They are having an ongoing fertility festival and egg-laying bonanza.

I have some chenggongensis youngsters, but too early to tell sexes.

Who knows, maybe there's a temperature or environmental control as with crocodiles?
