Snow Tessera?

It can't logically be a Tessera- there just simply has not been enough time to produce F2s since their discovery.

But it doesn't need an F2 to produce the trait - that's the point. "Heterozygotes express the mutant gene", to quote the Cornsnake Morph Guide. If a Corn is het for Tessera, then it shows as Tessera. It's not like Motley, where you need two Motleys or het Motleys before it actually appears visually in the offspring.

And remember that it will have been found in adults already of breeding age. If a breeder had holdbacks from a pair (and only one of which needs to be Tessera to show the trait), then they will already have F1 anyway. If either or both of the adults are het for Amel/Anery (let's face it, they're not exactly rare)- boom, Tessera Snows in F1.

And we're not taking into account the fact that serious, reputable breeders can work for a few years to test new genes before going puiblic. The announcement of the new gene doesn't come when it's first suspected. It comes when the breeder is sure that s/he has something new that can be genetically reproduced and isn't just a fluke from something like egg incubation conditions. Just because the general Corn keeping population has only just been told about Tessera, doesn't mean it hasn't been quietly worked on for some time now, behind the scenes.

While it's beautiful, there's no way I'd pay big money for it now when I'll be able to pick it up for probably not much more than a Stripe or Motley in a couple of years time. It's a pretty new Corn and won't ever be an investment in the same way that, say, Lavs were. I'm sure there will be some collectors willing to pay top dollar for Tessera hatchlings, but they won't be making a profit by breeding them.

I don't completely agree with you, you do need to wait for the F2 to produce morph tesseras just like you do with ANY other morph, as although the tessera part is dominant any other morphs it is being mixed with are not, so the F1 are going to be tessera het for X and Normals Het for X but you are still going to have to wait for the F2 to produce morph tesseras. So yes, you will get tesseras in the F1 but morph tesseras are going to take just as long to appear as any other morph.
 
Normal het Tessera, Amel and Anery x Normal het Amel and Anery?

I believe that combo does have a chance of producing a Snow Tessera in F1? Only one of the parents has to be Tessera or het Tessera, to produce it in F1. If a Corn is het Tessera, then it's Tessera.

In any case, we could well be on F2 for Tessera-derived morphs at the moment. We're seeing the end of the morph discovery/confirmation process, not the start of it.
 
There have been rumors about a guy in Kentucky having tesseras and I've seen pictures of amel, snow, and normal tesseras from this person that look pretty darn close to the other ones I've seen. It might indeed be legit but when you couple the unknown name and a low price it makes you wonder....doesn't it?
 
Here's my problems with it....
1 How much did he pay for the original tesseras in his collection/breeding group? $1000 +/-
2 Why would you create a double combination tessera and sell it so cheap? Crazy?
3 His other listing for a 1.0 regular tessera is really cheap as well?
Smoking hot Tessera Corn.
CBB LATE 09 Produced animal.
Eating weekly on live pinks.
Add this guy to your colubrid breeding projects and you could make some knockouts.
This is a corn you do not see everyday.
325.00 Shipped
or combine with the snow tessera in our other ad for 800.00 shipped
4 His normal tessera looks like something very different. There isn't really any reds in it. It looks like a caramel, but I don't want to read into it to far since it could be shopped or poor photography.

Things that make you go....huh?
 
It's not the real deal, he is scamming like last year.
It is pretty small from that pic.

I wonder if this is the same guy who had the "creamsicle" versions last year. There was a discussion about it somewhere in KJ's forum. I am too lazy to find it, sorry.

Either way, if it was pure, then the breeder would be an idiot to sell a morph male for such a low price when a pair of normals are still commanding twice what he wants for his pair. Maybe he doesn't have the real deal and knows it, hence the low price :shrugs:

I don't know what it is but doesn't look much like a tessera. Camby said earlier, which reminded me of that, this ad is hard to believe since he had that supposed pair of "creamsicle Tesseras" last year.

Yes, you do need the F2s to add a recessive morph in with the tessera gene. Yes you can get regular tesseras from the F1 batch but logically you still have to have F2s to add in any recessive gene you want, and tesseras don't just 'come' with het genes as the morph is too new. The only person I know that has Tesseras with het genes is Don Soderberg and anyone whom he sold them to THIS year- 2010, which wouldn't be a breedable age yet unless they were power feeding a male.

Edit to add in: Only others who had the original Tesseras were KJ and Graham so they would have Hets as well and would have possibly sold some. Who knows about the original producer of them? All I can say, is that the snow picture seems to have a lot of 'breaking' in the stripe pattern which isnt normal for tesseras, and the second picture of the 'normal' phase is not normal at all. You can go to either KJ's, Graham's or Soderberg's sites to see what a REAL Tessera looks like when it is newly hatched, it is darker in appearance and the black striping is already noticeable.

Also wanted to note:
Talking to Don on the phone about results from breeding the Tessera he has said that you can get some very strange stripes from breeding Tessera to a regular recessive striped morph. So, half the clutch would be the ACTUAL Tessera when the other half of the clutch would be still striped but the way Don described them is that they are almost a shadow of the Tessera- looking like the striped gene- but when the stripe breaks it then continues on. Don said that these were unusually different from the normal stripe pattern but WERE NOT Tesseras. He said he was selling these at the reptile show for a few hundred dollars. Maybe that is what this guy has? Even still though, he would need the F2s to produce coloration into the new pattern.
 
So, if one is Tessera shopping, one of the key elements would be an absolutely unbroken stripe? (Message to John- we're up to mating #4 now!!)

We had a few Tesseras born last year with broken stripes but the majority has a CLEAN stripe.

I email the guy but never heard back- He didn't get his animals from KJ, Don S. or I...... ?????? Heck, I was going to buy the darn thing JUST to see if it was a Tessera or not (never heard back from him). Next year I should begin producing Tessera morphs, BUT to date Don, KJ or I haven't produced anything (other than the weird stripe looking Tesseras- they have the tessera stripe but cool "clean" sides...I'll attach a pic of one of those also).

Graham, do the broken stripes just pop up in a clutch of otherwise standard tesseras?

I like that clean-sided look. Same question, did that just turn up in a standard clutch, or was there some sort of test breeding going on?

I thought I remembered something last season about snow tesseras, or amels, or something.
 
I got to say this guy has Tesseras after looking at that second link. That's a heck of a price for those.

Broken stripes have pop up along with "standard" Tessera clutchmates (not very often BUT from thw limited clutches we've produced so far).

I LOVE the clean sided look also...in person they are breath taking. I HONESTLY cannot answer that question fully. Hopefully this year we'll figure it out more. They did pop up the clutches along with "standard" tesseras... for now I'll leave it at that... the answers will be posted as we figure everything out.

I know those weren't clear answers BUT there has just been limited Tessera breedings so far... over the next year or two, many of these questions will get answered.

Cheers,
Graham
