Amel Tessera (no aka)
Most Commonly Used Name: Amel Tessera
Mode of Genetic Inheritance: Dominant
Morph Type: Single Dominant Mutation (Tessera) & simple recessive (Amel)
Eye Color:  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.

 

Adding the AMEL mutation to TESSERA, obviously results in an Amelanistic Tessera.  Because all Amel Tesseras are so close to original morph colors, expect to see more orange than red.  
 
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 dominant mutation, 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.


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). 

 

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.
