Пытаюсь весь интернет перевернуть в поисках информации по альбиносам - всё тщетно
Питомник (Nashira's Tonkinese) пишет мне по поводу последней фотографии: " I'm a genius; I already wrote a few days back that she was probably caca; that's a blue-eyed albino" и дает ссылку на свою статью:
The albino series (Himalayan/Siamese coloring, Burmese coloring, albino)
The albino series consists of five alleles. The gene for normal color, for example black, is dominant and is represented by C. cb is the gene that gives the paler color of the Burmese, the black cat becomes brown. cs gives Siamese coloring, ca gives a white cat with blue eyes, a blue eyed albino. This cat is not to be mixed up with the more commonly dominant white cat, which also can have blue eyes. And at last there is a gene called c. It gives genuine albino cats, which are white cats with red eyes. The cb allele is not fully dominant over the cs allele. A cat with the genotype cbcs has a coloring inbetween Burmese color and Siamese masking. The color of the eyes is turquoise. This coloring represents a special breed, not yet recognized in FIFe. It is called Tonkinese and cannot be pure bred. In a mating between two Tonkinese there is a 25% chance of getting Siamese masked kittens, 50% chance of getting Tonkinese and 25% of getting Burmese colored kittens. The Siamese colored kittens are born completely white. The color of the mask doesn't appear until after a week. This is due to that the cells of Siamese colored cat cannot develop any pigment if the temperature is too high. When the kittens are in the womb of their mother's they are warm and comfortable, and no pigment at all is developed. When they are born it becomes cool enough for the pigment to develop on the cooler extremities, like for instance ears, legs and tail. This temperature dependant pigment production is called acromelanism. Acromelanism is present in other animals, for instance in rabbits. The color snow leopard, present in Bengals, is primarily a masked cat with relatively weak contrasts between mask and body. The dots can therefore be seen all over the body, but the markings are a bit darker in the face, on the legs and on the tail. Foreign white is a Siamese with the gene for dominant white, W (see below). The result is a completely white cat with the dark blue eyes of the Siamese. A normal white blue eyed cat has considerably lighter eyes. Denominations: C = normal colour cb = Burmese cs = Siamese ca = blue-eyed albino c = true (red-eyed) albino
The gene which makes a cat pure white is dominant. This allele inhibits the normal function of the coloring cells, so that no color is produced. A completely white cat thus carries the genes for red/black, agouti/non-agouti, dilution/non-dilution, etc. The gene for white is thus epistatic. Pure white cats often have a color spot on the head when they are born. It disappears when the cat has developed its adult fur. This spot can reveal what color the cat has underneath the white. White cats can have yellow eyes, blue eyes or one blue and one yellow eye (odd-eyed). One doesn't know how the eye color in this case is inherited. White cats are often deaf. This is due to a degenerative change of the cochlea in the inner ear. It is definitely more common with deafness in blue-eyed white cats than in yellow-eyed, but there are yellow-eyed white cats that are deaf and blue-eyed cats with normal hearing. Cats can also be deaf on only one ear. Odd-eyed cats are often deaf on the ear which is situated on the same side as the blue eye. Denominations: W = white w = non-white The silver gene is dominant, and it inhibits the development of pigment in the coat. The under coat will be white, while the tip of the hairs will keep its colors. In an agouti cat the most obvious effect can be seen in the lighter areas, between the dark tabby markings. A silver cat that is non-agouti is called smoke. Denominations: I = silver (inhibitor of melanin) i = non-silver It is very unclear on how piebald white spotting is inherited. The generally accepted theory is that there is an incomplete dominant gene, S (spotting), which gives any amount of white spotting. ss would then signify a cat without white. Ss would mean bi-color (white paws and legs, white on the breast and white in the face) and SS would be a highly graded white cat, like harlequin and van. It is without a doubt not the whole truth. There must be more genes that modify the expressions of these genes, since there are not three sharply divided groups of piebald cats, but instead the variation seem to be continuous. Breeders of Birman can hardly be satisfied with the above mentioned theory. Birmans have white paws, and when two Birmans are mated all kittens get white paws. One never gets any cat completely without white and one never gets a harlequin or van colored cat. Hence one has come up with the theory of a recessive gene for white paws. This is denominated as g (gloves). GG is according to this theory a cat without white. Gg could possibly give a cat with a white medallion or a white spot on the tummy and gg would give white paws and maybe a bit of white on tummy and throat (these spots would be concealed in the light coat of the Birman). Now and then one sees examples of that these theories together are not enough to explain the piebald white spotting, but yet there are no other theories that explains this better. We must take into account that polygenes also are involved in this. Earlier one believed that chinchilla and shaded silver were only extreme varieties of silver agouti. Now many believe that there is a special gene responsible for these color variations (polygenes are also involved). The assumption is that this gene will cause to widen the light bands of the agouti hairs, which causes the whole hair, except the outermost tip, to become light. Even the single colored hairs on an agouti cat will be light. The gene doesn't work on non-agouti cats. The gene is called Wb (widening of band) and is incompletely dominant. WbWb gives shaded silver or shaded golden and wbwb gives a normal agouti coat. Cats with the genotype A- WbWb are also said to be tipped. On newly born tipped and shaded kittens one can almost always see signs of tabby/mackerel/spotted. The kittens will get lighter for a long period before they get their final coloring.
Julia59F, а для чего они вам генетику окрасов прислали? Я уж думала они по этой малышке что-то конкретное ответили. А генетику С, S и W мы все и так прекрасно знаем (в теории) Питомник тайских кошек "Blowing snow" Ничто так не украшает кошек, как колор-пойнт!

Julia59F, вот интересно, что-же всё-таки у вас получилось? А может и вправду какая-нибудь редкость вылезла, типа фавна (то, что не альбинос - это уже по-моему однозначно. Пойнты-то прокрашиваться начали...) Питомник тайских кошек "Blowing snow" Ничто так не украшает кошек, как колор-пойнт!

Каждый день ищу не по разу фавна я в этом которебенке, пока тщетно. Какие-то тени на носу вырисовываются вроде бы? Ни туда и ни сюда. Может к 4 месяцам прокрасится что-нибудь. Но, что это редкость - уже точно. Ждем и наблюдаем дальше.

какова судьба малышки в дальнейшем?
Говорят, что любителей экзотики много. Девочка очень нежная. Если фавн - однозначно себе, и, если никто не возьмет эту мировую сенсацию, тоже. Пока не загадываю так далеко, пусть поживет, самой насладиться бы ее обществом, чудная игривая и ласковая малышка. Заводчик - Юлия Константиновна Наша большая и дружная котосемья

Вот что они мне опять пишут. Это все мы и без них знаем. Nashira's Tonkinese:
" Julia, they cannot be Ccs, as C is full color. They would be Oriental self cats carrying point. My best guess is both parents are csca (or one could be carrying full albino c) and as cs is dominant over ca the point colors in the parents show in a normal way. Your white kitten seems to have inherited ca (=blue-eyed albino) from both parents..."
Julia59F, Юлия Константиновна, напишите уже им, что хвостик прокрашиваться стал и что это не альбинос Может они считают, что в России только с генетикой белых медведей и северных оленей знакомы?

А по каким признакам, если не секрет? Просто я этот окрас вообще не понимаю, а порой не вижу разницы с лиловым. Питомник тайских кошек "Blowing snow" Ничто так не украшает кошек, как колор-пойнт!
