Striped Tessera?

[Drewby07]

So after last year's serendipitous hatching of Sunkissed Tesseras, we bred out tessera boy to many more females this year trying to see what else is lurking in his genome....

Bred him to a normal gal and got 15 eggs. All have now emerged with the following results:

Tessera het. Sunkissed X Normal het. amel

5 normals
5 Tessera
4 Striped Tessera (?)

And a MOTLEY. :shrugs:

So I'm curious to see what you guys think might be going on here....

 

[Vinman]

nice animal you hatched out

 

[Drewby07]

Thanks Vin!

I can't tell the difference between a regular tessera and a striped tessera, so all I see is a tessera.

Don Soderburg hatched out some Striped Tesseras. You should check with him.

There seems to be something going on with the pattern of this Tessera neonate but the results you posted do not make sense to me.

Lets take this as a Striped (Tessera) for the Moment and you hatched a Motley as well in the same clutch.
I'll display my thoughts and thinking path based on recessive genetics and the dominance from Motley over Striped.

Logically it must be that one parent animal is at least het Striped and at least the other one is carrying both, het Motley het Striped - what changes the phenotype in this animal as its alleic to eatch other. Like this you can hatch both in Phenotype, Stripeds & Motleys.

Therefore Mum & Dad MUST both carry pattern gene(s) for providing a Striped and a Motley.

You write she's in phenotype a normal, so she could "only" carry maximum one pattern gene - hetero Motley or hetero Striped. Otherwise it would be expressed. Regarding that you hatched a Striped (Tessera) she is het Striped. And male carries both - As one animal of the parental generation needs to carry both for such a result.
But would Tessera Motley X Striped look like normal Tessera? Only if this would be no big change in phenotype it would explain that the male is carrying both.

What was your last breeding with this female Normal het Amel?
If both carry Striped & she was bred to a Mot last year that would be an hypothetical explanation of the results. Never heard of a double sired clutch, but yeah i'm not too experienced in this :sidestep:

Or it is no Tessera Striped.

My final opinion? Strange result. Keep & testbreed. LOL

(Hope you could follow my english... :dgrin

I can't tell the difference between a regular tessera and a striped tessera, so all I see is a tessera.

Typically the striped tesseras have no lateral "tesselation" marks. At the most, they seem to have some lateral striping at best.

That's what I remember reading somewhere here Camby. I'm still cloudy on the whole tessera x tessera = not tessera or something, but I'm sure a lot of people are.

To the OP, if that is a tessera and not a normal, then I would call it striped. I would call it a tessera as well because of the way the striping is. However, take my opinion with a grain of salt because I am not an expert in morphs yet.

What is the question? Is it a striped Tessera or a striped normal? The character of the stripe looks definitely Tessera-like to me- complete solid stripe, (except for the marking at the neck- which points away from normal stripe IMO) no cubing or vanishing, a dark border to the stripe, typical striped Tessera side pattern. It would be helpful, to me, to see the complete tail.

And what does the motley look like?

Circumstances like these are why I support the ACR- you could look back in mom's pedigree and see what her aunts and uncles were producing- to look for poss hets, and you could look at her offspring to see what they were paired with, if any stripes or motleys turned up in her grandchildren. Some day.

Thanks! I'll look for that identifying characteristic!

 

[Drewby07]

My main point here was.....maybe this "striped tessera" isn't striped at all....maybe it's a motley tessera?

I have checked with Don....he has gotten the same odd results. Here's what I know:

Both parents appear to NOT be homozygous for stripe / motley.

If both parents were het stripe, the motley hatchling would be impossible.

If one parent is het stripe and the other is motley....that explains the motley sibling....but that would also mean that the "striped tesseras" are actually motley tesseras, right? Even if genetically they carry a motley and a stripe allele on the same locus, phenotypically motley is dominant over stripe so these are motlies.....

???

Understand, I am not saying any "striped" animal without tesselation is a striped tessera, heck, not even in a tessera x tessera clutch with stripe present. I am just saying that in the tesseras that have been identified as striped also, there seems to be no tesselation and that is the main difference between them and a "normal" tessera. That and the fact that the striped tesseras seem to be the best stripes ever produced.

Make any sense?

My web connection is too slow to download pictures.

Mostly I agree with Drewby07. I'm coming up with two possibilities.
1. The striped Tesseras are really homozygous motleys. The Tessera gene interacts with the motley genes to produce more of a striped appearance.

2. Both the striped Tessera and the motley snakes really have a gene pair made up of a motley mutant gene and a stripe mutant gene (motley//stripe). The motley mutant gene is often not fully dominant over the stripe mutant gene. There is considerable variation in such snakes, from motley to a considerable amount of striping. Interaction with Tessera may increase the striping effect.

Mating the Tessera parent to a homozygous motley snake might help clear things up.

With the exception to the mark near the neck, it looks like a Striped Tessera to me. However you ratio's suggest on parent is het motley or stripe x motley. What does the rest of the clutch look like??:shrugs: I produced mine from a striped caramel x tessera/het stripe. Congrats on a Great looking specimen!

 

[Drewby07]

Pics to follow once they shed. I'm betting that my tessera is het stripe, and the female I bred him to is het motley....

Fully agree to this

 

[Drewby07]

Oddly enough, the "plain tesseras" from this batch exhibit some of the most perfect uninterrupted tessera dorsal stripe I've ever seen.....and weird fused belly checks almost giving them the "black belly" look.

Just goes to show ya....I think we will see a LOT more cool stuff coming from the tessera gene!

 

[guttatus.ch]

First 2 Pics show bellies as you describe as well, almost Black Belly style. This bellie pattern is from inside towards outside otherways than Black Belly.

In the 2nd pic you can detect that the dorsal stripe is unbroken - even tailwards where they are mostly broken.

Pic 3 is Tess. het Striped to homo Striped breeding - therefore sure het Striped
Pic 4 is from Tess. het Striped to non pattern breeding
Pic 5 is from Tess. het Striped to a het Motley breeding - perfect Striped.
About 1/4 of the animals had that belly shown in pic 1 & 2...

You see here is the same going on. All are fathered by the same male here, just different females.

 

[guttatus.ch]

Pic 1 shows the animal with the most expressed belly checks. Unfortunately it died after the 1st meal. What a shame!

Pic 2 is from Tessera het Striped to Het OR Homo Hypo Avalanche breeding.
A stunner even if its a normal & defo a keeper

We got some of those belly stripes in our 2nd Tessera clutch. Great looking babies!
