soloman5 Posted January 6, 2010 Report Share Posted January 6, 2010 As far as I know once an egg has been layed the sex of the wd has already been determined so the wd has it's dna from the start, then in incubation the sex is then determined by temperature, but dna does not change even though the sex of the dragon does. In theory a wd which was a male from the start but incubatored in female temperatures will develop but not as a full proper male so it probably won't have all of the male physical looks or be able to reproduce. If my thinking is right how does dna testing work when no doubt it is possible for alot of "female" dragons to actually have started as male so the dna would be invalid, and again in theory there could be alot of "male" dragons mistaken as females because they don't colour up since they were incubatored as female????? :roll: :roll: :-? :-? :-?

livingart Posted January 6, 2010 Report Share Posted January 6, 2010 is this new info that has come out? there are a few types of sex determination in reptiles, so what you are saying may well be a possibility Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted January 6, 2010 Report Share Posted January 6, 2010 the egg is only one half of the equation. if the temperature theory is correct for this species, a fertilised egg will develop over time into a male or female. no doubt it is possible for alot of "female" dragons to actually have started as male so the dna would be invalid, and again in theory there could be alot of "male" dragons mistaken as females because they don't colour up since they were incubatored as female????? No. it does not work that way at all. if your dna says you are a male, then you are a male. its not possible to trick those chromosomes into being another sex. there are exceptions for animals that can change sex at will / due to an environmental factor. I remember learning about embryonic develoopment in animals - the terms gastrula (makes the body structure i think) and bastula come to mind. google them and see what comes up. Again, I do not know if this holds true for WD's, but im pretty sure someone else on here does. and when temp determines the sex - it does so over a period of time when the eggs are being incubated, so that egg may develop into a male or female. it is not an instant thing, and freshly hatched eggs are not animals, they have no sex and have not developed.

soloman5 Posted January 6, 2010 Author Report Share Posted January 6, 2010 Does anyone know the chromosomes pattern for the water dragon, which would make it easier to work out. Quote Link to comment Share on other sites More sharing options...
livingart Posted January 6, 2010 Report Share Posted January 6, 2010 some reptiles don't seem to conform to scientific rules if it did happen as soloman has suggested then a raise in average mean temperature in their habitat may cause the extinction of that species the Thai water dragon P. coccinus (spelling) in papers i have read is chromosonally sex determined Quote Link to comment Share on other sites More sharing options...
soloman5 Posted January 6, 2010 Author Report Share Posted January 6, 2010 Just found out that wd's their sex is not determined by chromosome so what I wrote isn't valid oops :oops: Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 6, 2010 Report Share Posted January 6, 2010 Reptiles seem to come at this sex determination thing from a number of different angles. I hope that they are not psychologically damage because of this. I understand that beardies do not have a simple sex determination system either. It may be that it is quite simple but that we do not understand it. Quote Link to comment Share on other sites More sharing options...
Caryl Posted January 6, 2010 Report Share Posted January 6, 2010 Anyone got a cross dressing beardie? :lol: Quote Link to comment Share on other sites More sharing options...
Insect Direct Posted January 7, 2010 Report Share Posted January 7, 2010 maybe poss to get a genetic male thats female or something along those lines. Quote Link to comment Share on other sites More sharing options...
