The whole argumentation gets childish and I'm not going to keep the discussion going that way.
Well that's a shame, really. But providing arguments without facts and details pretty much goes along the same lines, I think.....

Wonna tell a computer science Ph.D. student about probabilities? Maybe we should discuss the probability of a single allel popping up in so many lines under different names like T+, Ultra and whatever. Many heaving to deal with Hibirds in that lines or at least signs of em. How often did Lavender, Caramel etc. pop up suddenly all over the lines? What are the probabilities, that Carols Rat Hibird also carries ultra by conincidence?
Sure! Being a student doesn't make anyone an expert nor perfect. Being a student means you are still learning. And trust me, I have had teachers who didn't have a clue about some of the things they were trying to teach.
As for the probability of that Ultra allele showing up under different names, I would say there is a VERY STRONG probability of that happening. How long has the Ultra gene been out there? For the greater part of it's existence it was thought to simply be Hypomelanism. I bought my original Ultras as young adults from Mike Falcon back in 1995 I believe. So assuming I didn't get the very first pair he produced, he was probably producing them for several years prior to that date. Certainly he did not keep all of those offspring, including heterozygous animals from those breedings. Quite likely there was a single point source for that gene and from offspring being sold over the years carrying that gene, it could have been spread to an enormous number of other breeders. Once it was bred to anything else containing Amelanism, something different would have resulted (which we now call Ultramel) but they would have applied their own terms to these different looking animals.
The probability that this happened this way is excellent, I would say.
Further, from what I understand, Andy Barr was involved in this project in some way (the actual relationship between Mike Falcon, Andy Barr, and Mike Shiver is not exactly clear to me, unfortunately) and at some point along the line gray rat snakes were brought into the equation. From what I recall from conversations with Mike Falcon, he said that he thought the original wild caught animal that "Ultra" came from was a naturally occuring hybrid between a corn snake and a gray rat snake because of it's odd appearance (color? pattern?), but later reversed his thinking on that. So if this one wild caught animal was the single point source of the Ultra gene, it certainly appears that not only did it get transmitted into corn snakes, but also into gray rat snakes via Andy Barr. As to what stock Mike Shiver was working with, that is anyone's guess.
While I am thinking of it though, you mentioned vague hints and suspicions about "markers" for hybrids. But you never mentioned specifically what these markers may be. Would you mind telling us what these markers are that you are seeing? And while you are at it, please relate how the differences in other lines of corn snakes that have various diversions in color, pattern, structure and actions are different in comparison.
Lavender got spread far and wide through a single chance selling of heterozygous animals to John Albrecht from my original source animal, which he then sold to various other people. Also, I sold off hets and possible hets for years as well, some before I even realized the Lavender gene existed. The original locality where I captured the animal carrying this gene is now a strip mall along route 41, so I suspect whatever wild population that might have existed carrying this gene may no longer exist.
As for Caramel, heck, I have no idea why there isn't an area that is knee deep in them, much as with the Anerythristics. I would think that gene would be a very positive survival trait in the wild, but to date have not heard of anyone catching one in the wild. At this late date, any that would come up would have to be suspect of being releases of captive animals carrying that original gene, I am afraid.

Maybe my experiences over the last years erased the god status you once had in my mind - but when reading this, I think I remember why I erased.
LOL! Since I never solicited such status from you, nor gained anything because of it, I can't see where I lost anything with your change of opinion. But it is interesting to note that your gods must agree with your opinions in order to hold that status with you.

You may have any right you want to. I was just stating, that vague hints and suspicions are enough for me to inform my customers about possible "problems". I learned this from the guys dealing with locality animals and I think that this is the most honest way to deal with such animals. And I feel I am within my right to say this, isn't it?
Sure, you can say anything you want. It's just that I am no more obligated to accept your opinion then you are obligated to accept mine. Anyone can come to any conclusion they want to based on any criteria they choose to hold as relevant. Back to the original topic of this thread, I head that another large breeder of cornsnakes has publicly commented that he believes the 'C' Anerythristic is a hybrid simply because it looks similar to other hybrids he himself has created. So does that make a Butter Stripe corn a hybrid because it looks somewhat similar to a yellow rat snake? At some stages of development a black rat snake can look VERY similar to an Anerythristic corn. Does that make Anerythristics a hybrid based gene as well?
I guess what I want to know is what is the criteria that people are using for their opinions? What exactly are these "vague hints and suspicions"?

As said - turn it around, maybe some rock solid evidence will from a rock solid source will appear and make clear, that the ultra allel is a corn allel. No problem. Otherwise, make clear that there is a possibility of it NOT being corn. And when speaking of logic, I think that people who accept it as a maybe hibird will not have any problem when it is corn. But the others that do care will not be happy if it is not corn. One direction doesn't hurt anyone, the other one does. It's you to decide which way is the more reputable.
But you can say that about EVERY corn on the planet. NO ONE can say with any absolute certainty that their animals do not have other species genetic influences in them. My comments along that line are always "as best as I can determine or have knowledge of", and that's the best that anyone can do. I would like to think that my corns are pure, but I have to be realistic. I wasn't around when the very first corn snake got created on this earth. Some of the sources I got mine from are unknowns beyond what I could see with my own eyes. Going by "vague hints and suspicions" I think I could argue well that just about any line of corn snake MUST be a hybrid because it looks vaguely different from some perfect classic example (whatever that may be).
So as far as this goes, yes, it may turn out that Ultra did originate from some hybridization 15 years or so ago. Yes, maybe some corn snake down in the Florida keys mated with a mangrove water snake and that union generated the 'C' anerythrism gene. Maybe Blood Reds are really the results of breeding corn snakes with everglades rat snakes. Maybe Sunkisseds are from breeding Florida kings to corns. Maybe Caramel corns are from some corn snakes romantic interest with a cow plop. Maybe all gray rat snakes in the wild are Ultras. Some of these are unknowable simply because the source of the information just does not exist. Others may be the result of purposeful intent. Some may be able to be determine accurately in the future, but I doubt any of them will ever be black and white.
Unfortunately that is just the nature of the beast with these critters. Anyone not willing to accept this probably should just go on to another line of interest. And I do not believe this is limited only to corn snakes. Because I seriously doubt it will ever be resolved, nor will it ever get any better. It is just what it is, and we have to accept it or leave it.
IMHO, of course.
ps: And just for the record, my stance is that if anyone asks me if my corn snakes are "pure", my answer is:
As best I have been able to determine, and to the best of my knowledge. If that is not good enough for you, and you believe someone else has an answer more to your liking, then that is a choice you have to make.
