Strawberry Anery 071611

This 2010 male Strawberry Anery is now 28″ long and eating frozen/thawed hopper or small adult mice.

Strawberry is the dominantly-inherited mutation that is believed to be responsible for the deepened pinks and corals seen in many compound morphs toDAY (most notably in the Coral Snow Types).  Strawberry is an allele to the Hypo A chromosomal locus.  Of course this male is also homozygous for the Anery A mutation, so he exhibits the classically grey/silver/white iris common in Anery A corns, but the heightened flesh tones in his markings and ground color zones is mainly owing to the Strawberry mutation.

2010 Opal Motley

Opal Motley (no aka)
Most Commonly Used Name: Opal Motley
Mode of Genetic Inheritance: Recessive
Morph Type: Triple Mutation Compound – Lavender, Amel, & Motley
Eye Color: Red pupil

 

Opal corns are the triple recessive compound of the three color mutations, Lavender + Amel = Opal & Motley.  Many Opal Motley corns look like ordinary Snow Motley corns, but some are what we call bi-colors, showing an orange or coral or pink ground color between dorsal pattern blotches.  There is usually no way to determine which neonates will mature to be bi-colors, but most of ours mature to have such colors.  Motley usually has a multiplier impact on the appearance of compound mutants, but in the case of light colored mutants like Opals, Motley’s impact is slight in some individuals and strong in others.


What to expect:
Hatchling Opals are often confused with Snow Motley corns, and even the ones that will mature to be bi-colored will often look exactly like Snow Motleys.  Most of the ones that mature to be bi-colored are actually Hypo Opal Motleys, but without knowing that for certain, we don’t charge more for those.  If we know they are actually quadruple homozygous individuals (Hypo Opal motleys), we do charge slightly more, but those prices will be published under the compound morph name, Hypo Opal Motleys if/when we have them.  Other than making the bi-color-ism more obvious, the extra mutation does not make them overly distinctive from those without the Hypo mutation.

2010 Fluorescent (Banded)

Banded Fluorescent (no aka)
Most Commonly Used Name: Banded Fluorescent
Mode of Genetic Inheritance: Recessive & Selective Variation
Morph Type: Selective variant of single recessive mutation
Eye Color: Red pupil


Genetically speaking, Fluorescent corns are Amel corns that have been selectively bred to promote their target look (red or orange blotches on an orange background, with separating white blotch margins), but we have taken this to a new and better version by selectively breeding toward stretching the markings from blotches to bands.  Since the only gene mutation they possess is Amel, the obvious distinction between Banded Fluorescents and the classic Fluorescent corn is the obvious banding.


What to expect:
 Neonate Banded Fluorescent corns vary little from their adult counterparts, with the usual exception of being more color saturated at maturity.  Expect to see little or no color or white clutter in all color zones, and thicker white blotch borders than typical Amel corns.  Colors can vary from one specimen to another, but all have more deeply saturated oranges and less reds than their Reverse Okeetee counterparts.  Bands will be obviously longer than their non-banded Fluorescent cousins, while some will extended to the ventral crest (anatomical junction of the lateral and ventral body zones).

Ultramel Tessera

INTERSPECIES  HYBRID

Ultramel Tessera (no aka)
Most Commonly Used Name: Ultramel Tessera
Mode of Genetic Inheritance: Dominant
Morph Type: Dominant & Recessive Mutation Compound
Eye Color:  Dark Red pupil & body ground-colored iris

FIRST, what makes Tesseras so expensive? Other than appearance, the primary (and inherent) value of Tessera-type Corns is their mode of inheritance.  Since they are dominant to wild type, pairing any Ultra Type that is a Visual Het to ANY corn snake (other than a Tessera-type) will render 50% Tessera mutants in the F1 (first) out-crossed generation.  The results of pairing an Tessera homozygote with ANY corn snake (other than a Tessera-type) will render 100% Tessera mutants.
See ULTRamel for an explanation of the genetic mechanics of the ULTRA codominant mutation.
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 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.

Combining the codominantly inherited, hybrid-derived color mutation, Ultra (co-dom with Amel mutations), with the corn snake pattern mutation, Tessera, yields a heretofore never possible genetic potential.  Instead of waiting two generations for the target product (Tessera Ultramel), when pairing an Ultramel Tessera with any form of Amel, you will receive some Ultramel Tesseras in the F1 (first generation) progeny.

What to expect:
At this early period in the Tessera’s resume, we still don’t know what phenotypic potentials exist.  So far, the only behavior that is atypical for a corn snake mutation is that many of the non-mutant siblings of Tessera types seem to have enhanced pattern and color features.  So far, I don’t see any hybrid markers, since the collateral sibling features to which I refer are – so far – in the realm of improving existing corn snake features (i.e. some non-Tesseras have better, brighter, cleaner, and/or more consistent colors and markings).
As hatchlings, Ultramel Tesseras look virtually identical to what you would expect to see in a Hypo Striped Motley; Hypo coloration with the pattern of an exceptional Striped Motley. Of course, the primary distinction is not visible.  It is that of the dominant-type inheritance from both Ultra/Ultramel (co-dom with Amel) and Tessera. We’re still not quite sure what to tell you about the adult appearance of Amel Tesseras, as 2010 was the first year they were produced here.  Updated pictures will be made available as they mature.

INTERSPECIES  HYBRID  – ULTRA / ULTRAMEL

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 containing 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 appearance, it was known that even if peoples’ snakes had the Ultra gene mutation, they would either be unaware or could avoid mentioning it.  Those of you out there that are boycotting HYBRID corns are advised to avoid acquisition of suspicious-looking corns with the word ULTRA in the morph description. Likewise, purists that admirably endeavor to promote only the genetically purest of corns are urged to question corns that have suspiciously abnormal features that have been historically identified 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 authenticity of pure corns, without obvious visual and/or genetic distinctions, identification of legitimately pure (or impure) corns is difficult at this time, if not completely impossible.

Ultramel corns are the heterozygous (hobby abbreviation Het) products of the Ultra mutation.  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.

Both Ultras and Ultramels render some of the most extreme examples of hypomelanism in corns, but a hypo phenotype is their genetic and visual function we recognize.  Some people call them Ultra or Ultramel Hypos, but I prefer to leave off the “hypo” since the chromosomal location of this mutation is the same as Amel (Ultra and Amel reside on the same locus of the chromosome).  Also, the hobby vernacular for the double mutant that is homozygous for both Hypo A and Ultramel would be Ultramel Hypo.  Upon hearing/reading these two words together, you would surely presume that the snake Ultramel Hypo is a double mutant.  Hence, those two words together are incorrect and confusing — when describing the single mutant, Ultramel or Ultra.  When you breed an Ultra type to a phenotype and/genotype of non-Amel, this mutation genetically behaves as a recessive.  Example:  Pairing an Ultra with an Amel results in 100% Ultramel progeny.  Pairing an Ultramel with an Amel results in progeny consisting of approximately 50% Amels and approximately 50% Ultramels.  Pairing an Ultra with a wild-type corn that is not het for Amel results in 100% normals (wild type) th

Whiteout13

Whiteout (aka: Blizzard Bloodred, Diffused Blizzard)
Note:  Expect DIFFUSED and BLOODRED to be incorrectly but synonymously used
Most Commonly used Name: Whiteout
Mode of Genetic Inheritance: Three Recessive mutations; Amel, Charcoal, Bloodred 
Morph Type:Single recessive mutations
Eye Color:  Red pupil

Whiteouts are the compound of three mutations that are recessive to wild-type; Amel, Charcoal, and Bloodred (aka: Diffused).  They are arguably the most white and unpatterned corn snake of all to date.  Many of them have a slight blush of yellow on the lower cheeks and neck, but it seldom goes beyond the neck area through maturity as does carotenoid yellow in other corn snakes.  Do not expect markings to be noticeable at maturity, though some may show faint markings when young.  

 
A brief history on Diffused mutants VS Bloodred mutants:
Initially, the corn snake gene mutation, Diffusion (formerly called Bloodred) was described as being recessively inherited, but many of the F1 generational heterozygotes exhibited some of the obvious features of the gene mutation homozygotes.  It is extremely rare for simple recessive F1 heterozygotes to exhibit ANY features of their recessively inherited genetic mutation.  For example, F1 heterozygous Amel corn snakes have no markers that demonstrate a hint of their simple recessive mutation, Amel.  The paradoxical partial-exhibition of the Diffusion mutation in the heterozygotes resulted in the Diffused mutation being re-described as having codominant inheritance (codom for short), but was tagged with the descriptor, variable.  At that time, variable codom seemed an accurate and satisfactory genetic description for the radical color and pattern diversity among members of this mutation, but far too many genetic anomalies persisted. Identification of the inheritance of this mutation is once again considered simple recessive, but the Bloodred corn that most of us identify with toDAY is virtually always the aggregate of traits resulting from the Diffused (new mutation name) gene mutation PLUS polygenetic traits promoted by selectively breeding toward the highest expressions of melanin reduction, diffusion, and red color saturation.
 
What to expect:
As neonates, Whiteout corns are sometimes faintly patterned (sides are generally faded or lacking typical lateral markings), but they will show NO YELLOW. Most (if not all) of them show head patterns that are notably unlike those of typical corns. ALL SMR Whiteout corns change dramatically through maturity, thereby rendering adults that are nearly devoid of head markings, side markings, (any visible dorsal markings they may have will be very faint), and little or no yellow.  Most of our breeders have NO yellow at all, but that doesn’t guarantee that all of their babies will mature to be devoid of facial yellow from carotenoid retention.  There will be NO belly checkering.  Many of the early Bloodred-type corns in the early 1990s were overly inbred and therefore suffered poor fertility (not to mention – the progeny of many of the first generations were stubbornly lizard lovers, refusing to eat pinky mice).  Thankfully, through out-crossing in our projects to improve or change colors and patterns, Bloodreds no longer rank high in the realms of sterility or reluctance to eat rodents.   In fact, there are some seasons in which Bloodreds are among the best feeders of our corn snake neonates.  Generally, next to Whiteout corns, Avalanche (Snow Bloodreds – aka: Diffused Snows) have the most white and least pattern.

Striped Tessera

Striped Tessera (no aka)
Most Commonly Used Name: Striped Tessera
Mode of Genetic Inheritance: Dominant
Morph Type: Both Dominant & Recessive Gene Mutations
Eye Color:  Black pupil with ground zone-colored iris
 

FIRST, what makes Tesseras so expensive? Other than appearance, the primary (and inherent) value of Tessera-type Corns is their mode of inheritance.  Since they are dominant to wild type, pairing any Ultra Type that is a Visual Het to ANY corn snake (other than a Tessera-type) will render 50% Tessera mutants in the F1 (first) out-crossed generation.  The results of pairing an Tessera homozygote with ANY corn snake (other than a Tessera-type) will render 100% Tessera mutants.

 
Striped Tesseras are at least homozygotes of the recessively-inherited STRIPE mutation and the dominantly-inherited TESSERA mutation. At this time, there appears to be no direct mutational relationship between those two mutations (when in genetic union), except for the seemingly collateral features that distinguish virtually all Striped Tesseras from simple Striped mutants. The features that are demonstrated in most Striped Tesseras that distinguish them from simple Striped corn mutants are:
 

  • Contiguity of pattern. Striped Tesseras have remarkably continuous striping and if it does break – unlike simple mutant Striped corns – it resumes in the same form – without fading to broken striping and eventually no striped pattern at all, as we see in ALL simple mutant Striped corns.
  • Stripe that extends to the tail and beyond.  I have never seen a simple mutant Striped corn that had a stripe that continued to the tail tip.  I’ve seen nearly full striping in some lines of Striped Motleys, but never in Striped mutants.  When one corn possesses both the STRIPE and the TESSERA mutations, most of these corns have striping that continues to the tip of the tail, regardless of how many stripe breaks there are between the neck and tail tip.  When the striped pattern of Striped corn mutants begins to break up and/or fade, it does not resume in recognizable form.  My reference to “tail pattern” is the dorsal location that is the polar opposite of the cloaca (polar as opposing points on the same vertical plane).
  • Variable stripe width. It is not common, but some of the Striped Tesseras we’ve produced have varying stripe width, which is something seldom observed on simple Striped mutants.  Generally speaking, the striping of Striped Tesseras widens as it extends tail-ward.  Some have intermittent and abrupt changes of width from the neck to the tail, but except for gradual widening of stripe, some have remarkably clean stripes.  The question that can’t help but be asked is, “In STRIPED TESSERAS, is the striped pattern the result of the Striped mutation, the striped version of the Motley mutation; Striped Motley. OR the striped version of the Tessera mutation?”  I don’t know the answer at this time. 

Note the comparison of a Striped Amel (Het Caramel) and a Striped Tessera in this image.

What to expect:
Striped Tesseras are still fairly rare. So far, the only feature that is atypical – compared to typical corn snake mutations – is that many of the non-mutant siblings of Tessera types seem to have enhanced pattern and color features.  So far, I don’t recognize any traditional markers that are unique to hybrid colubrids, since the collateral sibling features to which I refer are – so far – in the realm of improving existing corn snake features (i.e. some non-Tesseras have better, brighter, cleaner, and/or more consistent colors and markings).  I’m intrigued by the collateral nature of some of the non-Tessera siblings co-incidentally having improved characteristics without changing standard features of the species (i.e. body shape, belly checkering, head pattern, shape and number of markings).
 
As hatchlings, Striped Tesseras generally look like Striped corns, except for the precision of striping and retention of black pigment seen in most Striped Tesseras. Other than the obviously better quality of striping in Striped Tesseras, the primary difference between the closest corn snake phenotype (Striped Motley) and Striped Tesseras  is that of the dominant genetic inheritance of the Tessera.  Naturally, the Stripe and Motley mutations (which are alleles of the Motley locus) are inherited in recessive fashion. Just like all corns, Striped Tesseras gain improved color saturation as they mature. 
 
 
History of the Tessera Mutation:
In 2007, Graham Criglow asked KJ Lodrigue to order a 1.2 trio of Striped Motleys that were advertised on one of the popular Online Classified sites – since Graham’s job prevented him from personally receiving them at that time.  When they arrived, KJ discovered that they constituted a 2.1 reverse trio (two males and one female) instead of the advertised 1.2 trio (one male and two females).  KJ and Kasi recommended that Graham gift the extra male to me, and that’s what Graham did.  Profound thanks to Graham, KJ, and Kasi for that gracious and fortuitous gift.  In 2008, both the Lodrigues and I independently bred our males (Graham’s and mine) to novel (unrelated) corns. I produced about 24 TESSERAS (so named by the Lodrigues for the tessellated lateral markings) from over 50 fertile eggs, but since the Lodrigues were in the middle of a career move to another State, they were less fortunate, producing just four non-mutant Okeetee-looking corns.  My Tesseras were produced by the pairing of the male Tessera to three novel female corns (two F1 Locality Okeetees from Chip Bridges Rhett Butler Line and one Okeetee-ish female, Het for Stripe and Amel).  Imagine my surprise in seeing what we thought were nearly flawless Striped Motleys from three different females, only one of which was Het for a recessive pattern mutation?  After the first brood of 50% Tesseras hatched from the female that was het for Stripe and Amel, except for the perfection of pattern, I was not thinking new dominantmutation, but when both wild-type Okeetees produced the same results, it was obvious that a new mutation was discovered.

Upon receiving the reverse trio from the seller, we all commented on the mutual peculiarity of the phenotypes.  Most appeared to be the most perfectly Striped Motleys ever seen – in so much as their dorsal stripes were nearly contiguous from neck to tail tip (something never before seen in any corn snake pattern mutant) – but that was hardly possible if the admission of the breeder were true – that they were products of pairing a Striped corn with an Okeetee corn.  How could these descendants of a Striped corn bred to an Okeetee be Motley types, instead of Striped?  It is still unclear if those 2.1 Tesseras were F1s (first familial generation) or F2s (the originator of this line is now out of the hobby and difficult to reach – for clarification).  If these three Tesseras are F1s, my deduction is that the striped corn he used in the original pairing was actually Striped AND Tessera.  Even if those three were F2s, the likelihood of the mutant patriarch being a Striped Tessera is strong.

In the 100+ Tessera mutants produced by me as of Fall, 2010, I’m seeing the following features:
The most obvious advantage of having Tesseras in your breeding inventory (aside from their inherent beauty) is that because the mutation is dominantly inherited, 50% of every brood of corns from them will be Tessera mutants. With most other corn snake mutations, one must raise all the Het F1 progeny, and won’t receive any mutants until F2 reproduction (a task that can take four to six years).  In the course of adding Tessera to the myriad current patterns and colors of corns, an entirely new market is now in the making.

Predominantly contiguous dorsal striping is the most unique feature of most Tesseras.  Even when the stripe is broken, it resumes immediately thereafter (unlike Striped and Motley mutants whose dorsal striping never resumes with any degree of renewal). Roughly 1/3 of all that have been produced so far have no stripe breaks.  Another 1/3 or so have two to four stripe breaks, and the other 1/3 can have five to 20+ stripe breaks, but those breaks are merely interruptions of the stripe.  Not unlike very good Striped Motleys, many Tesseras have an interruption of stripe at the girdle (anatomical location – polar to the cloaca), but unlike Striped and Motley mutants, the dorsal stripe almost always continues to the tail tip.  Thus far, fully striped Tesseras have been produced from parents with some-to-many dorsal stripe breaks.  Hence, broken-striped Tesseras can produce fully striped striped Tesseras, even though their stripe is broken.  Incidentally, none of the original 2.1 original Tesseras in this line have complete dorsal striping, but many of their progeny and grand progeny do. 

More than 2/3 of the Tesseras produced by me so far have atypically large amounts of black pigment in their non-ventral pattern — a feature roughly 1% of all Striped and Motley mutants have demonstrated to date.  Less than 1/4 of all Tesseras produced by me have little to no black in their markings, and these are mostly Striped Tesseras.

The belly patterns of most Tesseras that are not also homozygous for other pattern mutations (i.e. Stripe) are all over the charts, but so far, all the bellies on Striped Tesseras have had no pattern at all.  Apparently, the STRIPE mutation trumps what normally occurs on the bellies of Tessera mutants, thereby not allowing belly pattern.

Having grafted another entire branch on the already sprawling corn snake family tree, we think the Tessera mutation will offer genetic flexibility never before possible; mainly in the realm of making Stripe and Motley types without losing the black (white in albinos).  Imagine all the current colors of corns infused with the Tessera, Striped Tessera, and Motley Tessera patterns?

2010 Kastanie Snow 071611

This 2010 Female Snow Kastanie is now 23″ long and eating frozen/thawed, large fuzzy mice.  Her depth of colors is great for her age, but will deepen more with age.  She is the second generation product of pairing a Snow to a Kastanie Bloodred (aka: Rosy Bloodred), so she is also possibly het for Bloodred. All mutations in this snake are inherited recessively; Snow Snow (Amel & Anery), and Kastanie.
