Kastanie / Chestnut... what are they?

[kimbyra]

The hybrid discussion can very well be done, but that is not an explanation for the genetical behaviour of the look. The Chestnut look is reproducable and doesn't act like a product of hybridization.

I'm sorry, I'm not trying to be rude, or even enter into this discussion since I have little to contribute to it, however, I'm confused by your statement. From what I've seen of hybrids, hybridization has a dramatic effect, including colors and patterns that have not been achieved before in the individual species alone.

Hybrids do not act in such a clear on/off fashion. These apparently do.

If you breed two snakes that look like normals, and some of the offspring look just like the parents, and the remaining offspring all show a look that is very similar to each other but different from their parents/siblings, this indicates the action of a single recessive gene.

Even if they are hybrids, a trait that behaves the way Menhir is describing would still be considered a Mendelian recessive.

Charles already explained it, but I can give you an example that I always use in german boards:
Breead a Germen Shepherd to a Dachshund.
Would you expect the outcome to be half Shepherd and half Dachshund or all animals something in between with a little variance?
I would expect the latter one and so IF these Mandarin look, we speak of the look, would be a result of hybridization, one wouldn't have a clear ratio of animals that look totally different and the other ones look totally normal.

None the less, one can also breed the leuzistic gen of ratsnakes into corns, breed for four generations only corns into the line and have leuzistic looking corns, but the gene itself isn't a corn gene. But that possibility is always there for every morph that exists - at least hypothetically.
I trust the original breeder that bought two normal looking corns in 1998 I think to show some snakes to his biology class, not knowing anything about corn morphs or the corn business.

Thanks guys!
I always appreciate when people take the time to explain things. :cheers:

The Schaub brothers called upon me to straighten out, that the postet picture is a 6 month old juvenile and not an adult. Herewith i inform you of my mistake. Feel very sorry.....

guys that's the snake i once was trying to describe.i will upload photo as soon as possible.i bought a pregnant female from germany and she gave birth to 11 eggs.3 of the hatchlings were ''weird albinos'' now identified as mandarins and the other babies had a normal phenotype.but 2 of these albinos didn't turned in true tangerine.the one has the tangerine colour discribed and mother has the chestnut phenotype.none of the babies reminds me the chestnut offspring which is pictured.the picture someone saw me once in this forum was so close to describe my baby but these photos here can ultimately picture my baby.i also didn't knew that the mother was chestnut phase because i hadn't ever seen such a phase.you will judge from the photos that i am going to upload.

that's my baby

another one

These cestnuts remind me a lot of a corn I saw in Reptiles magazine a few months ago. It was their morph pick of the month because it had started out looking anerythreistic, and had gone on to develop a dark red coloration on its saddles. Is this the same sort of thing that happens with chestnuts? Does anyone else happen to remember the snake I'm refering to?

I remember that and thought it was nothing more than a normal corn as normals, at hatching, are extremely dark and an inexperienced person might think it was an anery.
