Question for Ed and our more experienced science minded folk out there. Has there been any determination made as to whether SLS has a genetic component to it or has it been fairly well agreed that it's more of a parental nutrition and environmental (rearing temp) issue? I seem to remember last or maybe only I heard it was a parental nutrition and rearing environment issue and was not genetic but I could be wrong...

IF (and this is a big if) there is no definitive genetic component involved then I could not see any possible risk of this being passed on IF the SLS froglet was able to thrive and make it to adulthood and breed.... sound correct?

My reason for asking is this (and the moral question)... I have a froglet that morphed out with ONE spindly leg but the other front is fully formed and appears fine. I lost it in the tank for a couple of weeks and assumed it had died but low and behold I found it hopping around and supporting it's weight on the good front leg and it is apparently feeding and MIGHT perhaps have a chance to grow up. My question is this... should I put this froglet down simply because it has one spindly leg (IF it's not a heriditable trait as I suspect) or should I let nature take it's course and see what happens? Normally I would say put it down and let the next group of froglets make due but lets just say we're talking about a significantly higher caliber species of frog here and leave it at that. If this froglet proves it can survive should it be given a chance or should it be euthanized simply for the fact it's got one SLS limb that does not appear to significantly affect it's abilty to move around or feed? Thoughts?

In my experience and from what I have read ,it depends on a number of things. supplements, water quality, water temp. I'm not a scientist, but these are some of the things I have read and encountered. I'm sure Ed can be more specific. :)

I have a pretty strong belief that there are some genetic cases of SLS but I think these are rare occurances and are lost in the much larger number of SLS cases that are due to nutritional status of the adults, or other husbandry factors.
The unpublished study done by the Baltimore Zoo was pretty significant as they were unable to document SLS in properly supplemented adults.

You could just let nature take its course, but not breed the frog - just keep it as a pet if it survives.
