Anerythristic (aka: Anery, Anery A)

This corn snake (originally one word, we usually space between corn and snake) color morph is named from the Latin Anerythristic – loosely meaning no red or yellow pigment. Anerythrism best describes this morph because the most obvious missing color resulting from this genetic mutation is red. Another Latin term applicable to other snake species with this general mutation is axanthic, meaning no yellow pigment. Since red is the most recognized general color common to virtually all wild-type corns, its absence is more readily apparent. Having cited this lack of pigment, adult Anery corns nearly always have noticeable yellow – relegated mostly to the face, neck, and lower sides. The result of the retention of carotenoids attained from their diet, neonate Aneries do not exhibit this yellow – since it gradually accumulates throughout maturity. Adult Aneries that are devoid of yellow color zones are extremely rare in the hobby at this time.

Occasionally, we see Anery corns referred to as black albinos. We intentionally omitted this as an aka (also known as) because it is time for that name to disappear from the hobby, when referring to melanin-rich corn snakes. Modern perceptions of “albino” do not apply to such darkly-colored mutants. Ancient definitions of albino “may” have originally also applied to solid black (melanistic) animals (a common mammalian mutation), but that is now considered a colloquially incorrect term when applied to any wholly color aberrant mutant with obvious black.  I think it is nonsense to call a black snake ALBINO, since the word albino derives from the Greek albus – meaning white (which is the visual consequence of most non-reptile animals that lack color pigment).  Unlike mammals and some other animals whose colors are rendered as variations of their only pigment cell (melanin), albino snakes are often colorful (instead of white) in the absence of melanin – since snakes have color pigments produced by chromatophores AND melanin-producing melanophores.  Black Albino is an oxymoron in the realm of most snakes, and I believe its use in corn snake herpetoculture creates undue confusion.

What to expect:
Hatchling Anery corns are essentially black and white, since carotenoid yellow is slowly acquired from their diet – thereby manifesting slowly – as they mature. Most Anery corns begin to display that yellow around the face and neck between six and 12 months of age, and it spreads tail-ward the rest of their lives – relegated mostly to the sides of the body.

There is a reasonably dependable degree of color distinction between adult male and female Anery corns to tempt us to say that Anery mutants exhibit sexual dichromatism (aka: color dimorphism), but in so much as there are exceptions to this color distinction, the term does not accurately apply. An extreme majority (if not ALL) adult male Anery corns I’ve seen in my life had notably different coloration than their adult female counterparts. Males generally have earth tones (some shade of brown) in their ground color zones, their markings, or both – but a female exhibiting this color feature (without the aid of a separate mutation) is utterly rare. Most adult females are shades of black and gray (not counting carotenoid yellow attained from diet). Bear in mind that I refer to single gene mutant Anerys – since compound morphs can display colors that are attributed to polygenic or mutational traits derived from other genetic contributors. In most cases, male and female adult Anery corns can be visually distinguished at a glance, without the need to probe or compare tail conformation. This photograph is a typical example of this visual color distinction referenced above. This also applies to Ghost corns and some other Anery compound mutants, since they are homozygotes of the Anery gene mutation.  The color distinction demonstrated here does not apply to neonate Anery mutants.

 There are only three males in this group of sub-adult Anery corns produced by Nancy Wimer.

Thank you, Nancy.

 

 

 

 

 

 

 

 

The second anerythristic-type mutation discovered in corn snakes (Anery A was the first), Charcoal corns were originally named Pine Island Aneries for the origin of the first one to be discovered on Pine Island – off the Florida Coast.  Originally mis-perceived to be a variant of the Anery A mutation, the first one was bred to a Snow corn in a presumed effort to discern if the mutation was related to Anery A?  Subsequent generational results demonstrated that this was not an allele of the first anerythristic-type corn; Anery A.  There, if you breed a single-mutant Anery to a single-mutant Charcoal, you will get all wild-type progeny (presuming there were no other gene mutation copies common to both parents. 

Many of the original Charcoal corns lacked facial and lateral yellow.  Yellow was not common in the first generations of this morph, since early specimens apparently lacked the dietary carotenoid yellow trait/mutation common in most Anery corns.  Even toDAY, some Charcoal and Blizzard (Amel Charcoal) corns are devoid of yellow as adults, but in so much as that original specimen was quickly bred to a Snow corn upon discovery, the carotenoid retention gene(s) is annoyingly persistent in most family lines of Charcoals and Blizzards.  Breeding trials to identify the mechanics and inheritance of the carotenoid retention gene(s) are on-going.

 

 

Combining the three recessive gene mutations; Anery and Motley result in a beautiful compound most commonly referred to as the the Moonstone.  

INTERSPECIES  HYBRID

 

Note:  Ultramel is the visual heterozygote of the the mutation, Ultra.

Eye Color: Red pupil

 

This compound morph results from combining the color mutation Amel with the pattern mutation Motley. Colors can range from dull orange to red-orange, and the motley pattern may vary from only a few dorsal ground zone circles to many dorsal ground zone circles more than half-way down the back.  Adults are generally more colorful than hatchlings, but relative to the transformation of most corns from hatchling to adult, Amel Motleys change very little throughout maturity.  Amel Motleys should not be confused with Sunglow Motleys – regarding their noticeable lack of white.  One of the genetic functions of Motley is to reduce or eliminate color zones of white in albinos (black in non-albinos) leaving some to deduce that since Amel Motleys usually lack white, they must be Sunglow Motleys.  The primary distinction between the two is the obviously heavier color saturation in Sunglow Motleys vs. the slightly cluttered appearance of Amel Motleys (color zones that have a mixture of many different shades of their base color – and sometimes white stippling).

 

 

What to expect:
Amel Motleys are one of the rare exceptions among corns in so much as their appearance from neonate to adult changes very little. Expect mostly red snakes with ground coloration that is lighter than that of the markings – with notable reduction or lack of white around the markings. Some have only a few of the classic Motley dorsal circles (often resembling a chain configuration) while some sport a long and contiguous “chain” pattern nearly all the way to the tail. Never expect to see such dorsal circles ON the tail itself. BTW, the pattern mutation, Motley virtually always alters color and markings – if only slightly. Patterns are often less distinct and colors are sometimes slighted softened in Motley mutants – compared to non-Motleys. Some people call all Amel Motleys Sunglow Motleys because of the absence of white (single recessive morphs are mostly or completely devoid of white, so most people think the Amel Motleys without white must be Sunglow Motleys), but one of the genetic jobs of Motley is to greatly reduce or eliminate all black in non-albinos and therefore, all white in albinos.

 

 

 

 

Most Commonly Used Name: Strawberry Amel Mode of Genetic Inheritance: Strawberry is dominant to wild-type on the Hypomelanistic-A locus and Amel is recessive to wild-type Morph Type: Mutant compound of Dominant & Recessive Eye Color: RED pupil Strawberry and Amel mutations are the only gene mutations involved in this mutation compound. At this time, we believe that the Strawberry Mutation is dominant to wild-type and resides on the DNA locus HYPO-A. That is, when you breed it to any other corn snake, half the progeny should be Strawberries. How can you tell which half? Good question. According to Charles Pritzel’s Morph Guide (https://cornguide.com/) it is possible to distinguish between the two alleles at the Hypomelanistic A aka: Hypo A locus – both Hypo A and Strawberry – by microscopic inspection of the minute black speckling patterns on some scales. This is essential (in my opinion) because Strawberry Mutants can look identical to some Hypomelanistic Mutants. Important Note: These images are not renderings of the actual animals being offered, (except for uniquely offered snakes found in the SURPLUS section of this web site). We do not provide pictures of individual hatchling snakes for sale, nor do we recommend that you ever choose a new pet based on an image of its neonatal form. Corns change so dramatically from hatchling to adult, they will NEVER have the same colors or contrasts throughout maturity.While most of the snakes we produce will mature to resemble the featured adult image(s) on our web site, unlike manufactured products that are respectively clones of each other, the nature of polygenic variation results in each animal being similar but not identical to others of its morph. The snake we select for you may not mature to be identical to the pictured examples, but will be chosen based on our experience of observing which neonates will mature to properly represent their respective morph. We take this responsibility very seriously, and therefore publish the guarantee that we will exchange your SMR snake if it does not mature to be like our advertised examples.

 

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 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.

Go to History for more details about the DIFFUSED / BLOODRED base mutation of this compound morph.

This compound morph results from combining the color mutation, Amel with the pattern mutation Diffused.  As with most morph compounds that include the Diffused mutation, the Fire mutation‘s color affect is generally more diffused than a typical Amel corn, but nothing compared to Cayenne Fire mutants that possess the additional Red Mask mutation. Except for some of the color and pattern variants of this mutation compound, Fires arguably have much less color contrast than typical Amels and generally redder coloration. Expect dramatically reduced white margins, compared to most non-pattern Amel type mutants. 

 

 

What to expect:
Many Fire hatchlings look like little more than regular Amel Corns, but the head should have some form of Bloodred head pattern, and the belly will be devoid of classic Amel Corn snake white & off-white checkering.  The belly pattern can have colors – and even pattern – but not organized checkering.  From a short distance, adults appear to be completely red or red/orange, but upon closer examination, most have a faint blotch pattern, and some will have minute traces of white on the scales around the posterior-most dorsal markings.

At this time, this author suspects that P/S Bloodreds owe their atypical white lateral and facial markings to polygenetic traits versus simple recessive mutation. It is sometimes difficult to determine the inheritance of a trait or mutation when expression of the atypical feature is highly variable.  In other words, are the Bloodred siblings of P/S Bloodreds not P/S Bloodreds OR are they P/S Bloodred mutants that are at the lowest end of the 0-to-10 scale for white expression?  When proving the mode of inheritance via evaluation of Mendelian Phenotype Proportions in a single brood of snakes, visual expression is crucial.  Hence, if the expression of white in this morph can be so extremely variable, when citing the ratio of visual mutants compared to visual non mutants, the very description of inheritance can be in doubt.  I therefore honestly don’t know if P/S Bloodreds owe their distinctive pied-sided white appearance to a recessive mutation OR polygenic trait modifications.

Aside from the random lateral white feature that is obvious in most members of this morph – compared to standard Bloodreds – is the extreme diffusion – even if they don’t demonstrate any of the randomly distributed white patches on the sides.  On most – even in the absence of lateral white patches – there is an obvious line of demarcation between the dorsal and lateral pattern fields – just above the half-way point on the sides (dorso–laterally).  This stark break line between dorsal and lateral markings also begs questions about the lateral white being a mutation OR variable expression of polygenetics.
