Info Tokanese!

[Ritzie/Admin]

Ok, some of us had discussed the tokanese colour. Tigru mentioned it and others didn't know what it exactly was (including me). I saw that Tigru had asked on a large Dutch gerbil forum, so I will place here some info that I have found there!

Some said that a tokanese a bad coloured siamese or burmese is. So a burmese that is too light and/or a siamese that is too dark. So infact are they bad coloured burmese and siamese! Tokanese as a colour doesn't exist.

Someone else said that she had heard from Karin van Veen, Vera Brückmann, and Fred Petrij that a tokanese the same is as an "grey siamese" A grey siamese is a siamese with Gg!
So the colourgenetics are than: aa cbch D- E- Gg P- spsp.
The g caused to delete the yellow pigment in the hairs, so that the black will become more visible! Thus darker siamese!

What do you think?

Would Tokanese include gg Siamese too - ie: light CP slate? I have noticed that there is a small difference between GG siamese and burmese and the Gg siamese and burmese. The Gg gerbils are slightly darker in colour. The colour difference, however, is not as obvious as in the light cp slate and cp slate.

In my personal view a gg siamese is just a light cp slate! Not a tokanese.

OK, this discussion has also started again on the Dutch gerbil forum! And Karin van Veen (from the website: Gerbil Information Page) has said there:
"A grey siamese has 2 small g's, and is the same as a cp slate. Inside the NMC (Dutch rodent society) this colour is called Tonkanese. It is not a scientific name. But the colours of the siamese and the burmese can vary a lot, especially by temperature changes there are a lot of different shades possible, and not everyone knows how its animal's genetics, so a dark siamese will be quickly called a tonkanese. Prove of that can only be given through a test-crossing, thus with a gg animal. From a crossing between a dark burmese/tonkanese with a grey agouti will come 100% grey agouti pups, thus than have both parents 2x g. Test-crossings are always handy, an animal which can be used well for this is a separator. That is an animal with only recessive genes, except for some. A aaCCddeeggpp animal is called a C-separator. If you have e.g. a golden agouti, and you want to know if he carries recessive genes, you can crosse him with such a C-separator. Will all pups be golden agouti, than the golden agouti has no recessive genes, but when you will have black pups, than he will have one a, etc."

So in the Netherlands they mean by a tonkanese, just as you all mentioned here a CP slate!
