dont recall seeing your screenname before.
No argument from me on any of your several points. Interesting your statement of 5-10 generations, I'da thought the top zoo's & Florida reptile gardens had been doing it for ages...
Again, I ponder how much variability originally existed & is selected for by the several breeders who frequent this forum...
:Aggression can certainly be linked to genetics in some cases (as has been clinically proven in mice...the research for this can be found on dozens of sites, and particularly on the JAX website), but that doesn't mean that it always is.
:I didn't re-read the responses before I posted this, but it seemed to me that most of the replies indicated that as long as the male was well fed and carefully introduced, the particularly violent matings were very few and far between?
:How many captive generations of indigos have there been? I'm guessing it there haven't been more than 10, and I would probably guess it's closer to 5. Even if the breeders had originally selected the nastiest (term used loosly, since from what I've heard even wild specimens are usually pretty calm) easterns they could find, and directly imbred every generation based on the most aggressive animals from each clutch...they would only just now (6-10th generations) be beginnning to isolate the "aggresive" genes. (which doesn't mean it wouldn't surface, just that it would still be appearing in a fairly random manner). We're pretty sure this hasn't happened by accident, since most breedable indigos are bred (regardless of temperment).
:I'm not at all trying to trash the theory here...I'm just saying I find the proposed conclusion unlikely. It seems to me that the main message coming from the previous thread was that most of the violent matings probably could have been less violent if the conditions had been slightly differnt. We're still learning about these guys...give the breeders some time and they'll get it worked out. As they're fond of saying, indgos aren't "formula" snakes...but in years to come they will be.
