Comments: Feeding on frozen/thawed adult mice. This 2010 female Ultramel Het for Caramel is now 43″ long. She brumated (hibernated) from October 10, 2012 to January 31, 2013 so after some fattening, she should be ready to breed in a matter of weeks.
Mode of Genetic Inheritance: Codominant with Amel, but recessive to Wild-type
Note: Ultramel is the visual heterozygote of the the mutation, Ultra.
The founder (discoverer) of the Ultra mutation states that he originally paired a gray rat snake with a corn snake, in the discovery of this mutation. By the time most of us were made aware of the HYBRID origins of Ultra types (originally named Ultra Hypos), we had already bred it into many other corn snake mutations. It was therefore collectively decided that in so much as it would be virtually impossible to track down (and eliminate) each and every snake possessing a form of the Ultra gene (surely thousands of individuals in the collections of hundreds of breeders and keepers), the mutation would be treated like other pure corns. In so much as it generally did not alter the corn snake pattern, some breeders could be unaware they had it, while some could avoid mentioning it, if they did know. Those of you out there who are boycotting HYBRID corns are advised to avoid acquisition of suspicious-looking corns with the word ULTRA in the morph description. Likewise, purists who admirably endeavor to promote only the genetically purest of corns are urged to question corns that have suspiciously abnormal features that are historically regarded as hybrid markers. Not that all such markers are proof of alien origins. Especially because of the difficulty and expense of formulating a DNA base line for all North American colubrid snake species, and in the absence of expensive DNA testing to identify the authenticity of pure corns, without obvious visual and/or genetic distinctions, identification of legitimately pure (orimpure) corns is difficult at this time, if not completely impossible.
Ultramel corns are what we call the Visual Het version of the Ultra Mutation. Virtually all heterozygotes of mutations that are recessive to Wild-type are indiscernable, when compared to their non-Het siblings. At SMR, we seldom offer the homozygous version of the Ultra mutation because there is a subtle and often indistinguishable difference between the Homo (Ultra) and Het (Ultramel) versions. Genetically speaking, Ultras are the powerhouse genetic version of this mutation in so much as when you breed one to any Amel corn snake, 100% of the progeny will be Ultramels. Breeding Ultramels to Amels results in approximately 50% Ultramels and approximately 50% Amels. Generally, Ultramels are more colorful than Ultras, but there are exceptions in both directions. Breeding an Ultra type to any non-Amel corn will result in NO Ultra types, since Ultra is recessive to Wild-type.
Other than appearance, the primary (and inherent) value of Ultra Type Corns (Ultras and Ultramels and their color and pattern compounds) is their mode of genetic inheritance. Since they are co-dominant to Amelanistics, pairing any Ultra type to ANY Amel corn (or Het thereof) will render some Ultra types in the F1 (first generation) of out-crossing to non-Ultra type corns. The results of pairing an Ultra-type with a non-Amel corn (or Het thereof) will render Mendelian results that parallel recessively-inherited mutations; no Ultra-types will result, and all progeny will be Het for Ultra when bred to non-Amels.
This is one of the few corn snake morphs that you should not purchase based on a pictorial example. This is because of the extreme diversity of appearance within the mutation/morph. I could easily make this statement about most corn snake mutants, but the reason I do so here is because the real value of this mutation is its’ mode of inheritance. Few corn snake mutations are inherited in dominant fashion, so the primary reason most snake lovers purchase Ultras or Ultramels is because when they breed one to any snake with a form of classic amelanism, approximately 50% of the F1 broods will be Ultra-type mutants (or approximately 25% – in the case of breeding the an Ultramel to a corn that is het for Amel and 100% if you breed an Ultra to an Amel type). I think you will be amply satisfied with any phenotype you receive from an Ultra type, but should you choose to buy one based on the sample picture on any web site, you may be disappointed if yours does not mature to be exactly like the one that inticed you to purchase.
