One paragraph, No way!
A brief paragraph?! It would take several I am afraid to begin to explain the group of Hypo morphs that currently exist within corn snakes. Some are known, some new hypo morphs may exist and many Standard Hypos are being called by a never ending list of trade names. Much like the amels trade names, Sunglow, Candy Cane and so on, but for some reason, when a new phase of hypo comes along, it seems to not be connected with or is intentionally not connected with the Standard hypo gene. Perhaps the hypo gene involved is just not known, because there are more than one.
Which are compatible with which, or perhaps a better way to think about it, which are not compatible with which? It should be assumed, in my opinion, that all hypos are the standard hypo gene unless claimed to be otherwise.
The standard hypo gene most of us know has been around for a very long time. It is referred to a Type A hypo and has been called many things such as Rosy Corn, Super Hypo and on and on. The second hypo gene that proved to be incompatible with the standard hypo gene is the Sunkissed Hypo, and is called Type B Hypo. The Standard hypo and Sunkissed hypo were bred together and normal hatchlings were produce which proved they were incompatible and different hypo genes.
A few other hypos seemed to pop up and were given different trade names. Ultra, Pumpkin, Dream, Christmas, Strawberry, Red Phase, Yellow Phase and more, but they were not tested against the two previously known hypo genes and were not stated to be the standard hypo gene. Perhaps it was even strongly suggested that they were not the standard hypo gene and perhaps a new hypo gene.
I had a hypo pop up out of my wild Okeetee line, that I suspected was a new hypo gene. It has many characteristics that were very different than the other two known hypo genes. I was not alone. Some of the other trade named hypos can be linked back to wild caught stock as the stories go. I decided to test bred this hypo that popped up in my collection against the other two known hypos. I bred this potential new hypo to the Standard hypo and got all normal hatchings. I also bred them to the Sunkissed hypo and got all normals babies. My conclusion was that this hypo that popped up in my colony was in fact a new hypo and it has been referred to as Type C hypo and is currently named Lava Hypo. I previously called them Transparent Hypo. I call the pure line from wild caught stock, Lava Okeetees, and all out crossed corns which are homo for the Lava hypo gene, Lava Corns.
So we now have, Standard hypo, Type A, Sunkissed Hypo, Type B, and Lava Hypo ,Type C. There may be more that exist right now, but others have not test bred their potential new hypos against the known hypos. I did and was next in line for the Type C listing. Others could have tested theirs, but have not.
I am interested I finding out more information, as many other people are, about the compatibility of Trade named hypos. Without the knowledge of which type hypo gene your snakes are caring, there can be compatibility problems and further mixing of the hypos to cause even more confusion than already exist.
Some hypos genes have already been mixed up and causes questions about their compatibility with other hypos. The Ultras Hypos are a good example. The Ultras have been bred to the Standard hypo and Sunkissed hypo and normals have been produced, which makes the Ultras incompatible with these two hypos. The problems is that some Ultras when bred to these two hypos produce half litters of hypos, which highly suggest that some Ultras have at least two hypo genes in the mix.
Since Mike was wanting this short and it is very long already, I will give a brief history of the story behind the other hypos we are testing the Lavas too. The Christmas hypos are linked to wild caught stock, but have not been tested against other hypo, except maybe the standard hypo. The Strawberry Hypos came for stock from a Zoo and were called Ultras at one time, but perhaps not the same as the others known as Ultras. They really do look like strawberries, so the name is fitting, but again, they have not been tested against the other known hypos. Dreams involve a wild caught light Okeetee, but were bred to an Okeetee Phase with no known background purchased from a breeder. It is very possible that the hypo gene involved came from this Okeetee and not the wild one and is most likely the standard hypo gene.
Compatibility is the issue. We have three known hypos that have been test bred and they are not compatible with each other. The problem is that the hypo gene involved to produce many of the hypos gets lost when animals are sold and especially in the wholesale market. So far an amel is an amel no matter where you get it, but a hypo without background info is an unknown genetically, due to the fact there are several incompatible hypo genes that are known to exist and perhaps more.
If Kats test breeding between her Ultra X Lava produces normals hatchlings, this will prove, or for the critics, highly suggest that the Ultra is a new hypo gene and deserving of a Type D listing. Kat’s Ultra has been tested against the Standard hypo and presently she has eggs from an Ultra X Sunkissed breeding incubating. Others have bred Sunkissed to Ultras and found they were not compatible.
Funny Misty! I do have many of the location of the treads on my computer, but they are not hot keyed. LOL I suggest anybody that is interested in learning more about the hypo talk on the forum do a search on this forum and they will find many threads about hypos and the current mess they are in. Use key words like “Hypo”. “Sunkissed”, “Ultra”, “Lava”, “Transparent” and any others you may come up with.
Another good source of info on the subject is Serp's new book "The Buyers Guide to Corn Snake Morphs" or the Love's "Corn Snake Manuel". A must have and must read for anybody interested in corn snakes.
