What kind of frog was it? I suspect enough inbreeding might cause something like this to occur....
Froggers talk about genetics, you just need to know where to look
Smack, I think it was a Patricia although I'll have to verify. Adults are very well documented so highly unlikely (but not impossible) that there is a line breeding problem. This is the first of any issues for the parents in what is likely hundreds of offspring.
Speaking with huge ignorance, I was just curious if it was a genetic anomaly or if it could occur during egg handling. Having written it here, it sounds like a stupid question. I suspect that it's just a freak thing that happens, with no intelligent way to speculate on cause, with the exception of your comment of course.
Doug, that is very interesting. Care to speculate on what was causing it since this ain't exactly your first rodeo?
