GENETIC Difficulty

[SickPyth7]

As my last regular 2012 clutch is hatching I'm learning that it may cause me more trouble than I wanted! The parents are (m) Tessera het snow stripe bred to (f) Caramel MotleyPin het hypo stripe. So far every baby shown in the eggs are Tessera or Stripe Tessera!

Or are they?

Tessera in general is extremely identical in appearance to the MotleyPinstripe. So are all the babies Tessera or are some MotleyPinstripe? How can you tell the difference when they look the same? Don't say the belly cause some Tesseras out there have no belly pattern! So how do you sell them?

This thread affects many Tessera breeders, how do we define the babies to sell?

Striped tesseras tend to be "perfect" stripes. The stripe goes to the tail tip, and the lateral striping typically is unbroken and continues to the tail tip as well. On normal stripe, the pattern usually begins to fade out, and the lateral striping rarely continues for any real distance down the animal.

This is true surrounding Striped Tesseras, but now throw Motley in there! How do you know considering a MotleyPinstripe that is fully striped can look exactly like a Stripe Tessera! I know cause I have produced many Fully Striped MotleyPins. There is very little if any at all difference.

I was told it was the mosaic pattern on the sides. The tesseras have the pattern and the pinstripe motleys don't.

I don't believe striped Tesseras _do_ have the "tessera" pattern on the sides, though. A striped Tessera does not have that classic Tessera look. So, you ask yourself, what is the point of a striped Tessera? It's for people who like the look of a perfect stripe all the way to the tail, instead of a vanishing stripe.

Exactly! That is definitely one of the main reasons for the Striped version of Tessera. It is Motley with Tessera that maybe the gene that hurts Tessera! I know when I produced an Amel Tessera this year I also produced 3 Amel Motleys in the same clutch but cannot prove if they are Tessera or not, this is what kills me!

Well- it will be a nice surprise for someone!!

Nanci this is true. It's just to bad it couldnt be more noticeable! More test breedings may help. When I get home tomorrow I will post pictures of the clutch I have a feeling the majority look Tessera.

13 of the 17 babies are Tessera or Stripe Tessera.......the other 4 look Motley but could be Motley Tessera....How do you know?

You could send a pair this way since you dont like them. Lol sounds like you got some fun testing ahead of you

Might as well toss this wrench out here.
Here's the first female's belly, looks motley-ish.

here she is again, on the top.

She doesn't have much going on in the way of the broken-up side pattern.
Striped Tessera. Is that like saying Salt Water Tuna? Aarrgghh.

I think it would be helpful to see the babies full patterns, not in a pile.

Have you looked at John's charcoal tessera thread?

If you have a copy of the 2010 CMG, there is a suspected tessera motley (photo by Don) which looks quite a bit like the "stripes" in this clutch. A break at the neck, then a full narrow pinstripe the whole length of the snake.

My question is, are you positive the Tessera parent is het stripe? (not het motley)

So your Tessera parent would have one M+ (wild type) gene and one ms (stripe) gene.

The mother has one motley gene mm and one stripe gene ms.

You should expect 50% tesseras. Of those, half should be regular tessera patterns.

Of the 50% non-tesseras, shouldn't half of those be normal wild-type saddle patterns?? Why don't you have any of those? Just lucky??

I'm not sure where I'm going with this. You could either have 1/4 motley tesseras and 1/4 motleys/pinstripe motleys, or 1/8 striped tesseras + 1/8 motley tesseras, 1/8 stripes+ 1/8 motleys/pinstripe motleys, right?

I like striped Tesseras, but I think I'm going to try to steer clear of it for now...

Actually Nanci that is a great question. I have produced in appearance to be both Motleys and Stripes from my Tessera.

Here is the Snow Stripe I produced from breeding to a Snow Stripe....but here is one I suspect to be Tessera Motley or Tessera Cube from that same Snow Stripe.
