With most other corn snake mutations-which are recessive to wild type-one must raise all the Het F 1 progeny, and won't receive any visual mutants until F 2 reproduction (a task that can take four to six years). Presuming that you are breeding a Visual-het-indistinguishable from their homozygote counterpart-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 visual-het Tessera mutants (they will look like homozygote Tesseras, but will only possess one of the paired Tessera gene copies (unless you are fortunate enough to possess a Tessera homozygote). In the 100+ Tessera mutants produced by me as of Fall, 2010, I'm seeing the following features: some non-Tesseras have better, brighter, cleaner, and/or more consistent colors and markings). 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. So far, the only genetic feature 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. Since he called the reverse trio STRIPED OKEETEES, it's more likely that their parents were a classically patterned Tessera and an Okeetee, instead of a Striped mutant and Okeetee?Īt that early period in the Tessera's resume, we didn't know what phenotypic potentials were possible. Even if those three sub-adults received by KJ and Kasi were F 2 s, the likelihood of the mutant patriarch being a Striped Tessera is strong. If these three Tesseras are F 1 s, my deduction is that the striped corn he used in the original pairing was actually Striped AND Tessera. How could these descendants of a Striped mutant corn bred to an Okeetee be Motley types, instead of Striped? They were incorrectly identified as striped mutants? It is still unclear if those 2.1 Tessera sub-adults were F 1 s ( first familial generation ) or F 2 s (the originator of this line is now out of the hobby and difficult to reach - for clarification). Advertised as Striped Okeetees, they appeared to be the most nearly 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 citation of the genotype of the breeders were true-that they were products of pairing a Striped corn with an Okeetee corn. Upon receiving the reverse trio from the seller in 2007, we all commented on the mutual peculiarity of the phenotypes. 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. My Tesseras were produced by the pairing of the male Tessera to three novel female corns (two F 1 Locality Okeetees from Chip Bridges Rhett Butler Line and one Okeetee-ish female, Het for Stripe and Amel). 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. In 2008, both the Lodrigues and I independently bred our males (Graham's and mine) to novel (unrelated) corns. Profound thanks to Graham, KJ, and Kasi for that gracious and fortuitous gift. KJ and Kasi recommended that Graham gift the extra male to me, and that's what Graham did. 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). 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.
