What is the definition of the word S C I E N C E? Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

Our choice was based on the fact that there is  NO CHOICE: If you want to breed Siberians, that is.
Color point gene does not belong to Siberian gene pool, it is a fact and even if the mutation was brought in, it shouldn’t have been encouraged even less bred. If nem exists nowadays it is simply because POOR choices were made, because of ignorance and also because of demand and economical reasons and later political reasons.

This page explains the origin of CP pattern mutation and the fact that the only natural CP cat is the Siamese. We also discuss silver, a natural mutation in forest cats such as Siberians, and finally, the classic pattern, an ancient tabby mutation that is totally normal in Siberians.

Here is a link with all the breeds and their birthplace in a study by Lesley Lyons (PHD genetics), Monika Lipinski and Barbara Gandolfi (PHD Biotechnology) for Lyons genetics feline lab.

Variation of Cats under Domestication: Genetic Assignment of Domestic Cats to Breeds and Worldwide Random Bred Populations


About silver:

SILVER is a natural, dominant mutation in these cats, and I spent long hours of my time going through Roy Robinson’s data regarding the silver mutation and other publications, silver is certainly a natural mutation that appeared EXACTLY in forest cats to start.
Extract from Roy Robinson’s book and Lyons Feline Genetic Laboratory website.
Silver (a.k.a. Inhibitor (I,i)) appears to reduce or eliminate the production of pheomelanin or yellow pigment in the cat’s hair. Generally considered a dominant trait, one copy can cause the loss of pigment, but likely a cat with two copies of the mutation may have less “ruffusing” or “tarnishing” as well. On a tabby cat, the black banding will appear but the yellow bands are devoid of coloration. (Figure 1) Silver is seen in random-bred cats and may be a very ancient mutation, pre-dating the development of breeds and the cat fancy. Many argue as to whether there may be a second–recessive type of silver mutation. I personally do not think this should be ruled out until we prove otherwise, but I think the majority of evidence (or cats) is for a single dominant mutation. There may be more than one mutation, we will see! Cats that are non-agouti (aa) and are solid, will appear as smokes, with white at the base of the hair when they have the silver mutation. Silver is a novel gene in cats, all the genes that cause silver colorations in other species have been eliminated as the cause.

They are looking for samples; contact the lab if you can contribute.  I am sending my Homozygote silvers.

About the classic pattern:

Longhairs” as they were called pre-1900 were intermingled with British Cats very early in cat fancy history. Since the Norwegian Forest Cats and Maine Coons have a high penetrance of this trait, I think we can consider this a very widespread allele in Northern Europe and Russia. Classic tabby has always just been considered an “ancient mutation”.
The classic pattern was already present among the domestic cat population, mixed with Felis Silvestris Caucasia, which originated with the Siberian cat.
Any mention that the classic pattern is a foreign pattern to Siberians is pure nonsense but a very used allegation repeated by nem mixers who repeat nonsense “they heard”.


Here is also a presentation about golden made by  Alex Kolesnikov and his theory about golden in Siberians:

P: This article was removed since the Golden Gene is now known and I will post shortly articles about it

At Clean Genealogy, we are testing older essential cats to obtain genetic identity cards and raw data from older Siberians like Charisma Dostoyanie Sibiri, Busik’s daughter, Sharlotta Adagio, Yasha’s granddaughter, to obtain genetic markers and genetic material to maybe get further analyses in the future using the raw data.

All Clean Genealogy studs and queens are tested with MY CAT DNA, and in the future, all Clean Genealogy kittens sold will have a DNA-certified pedigree for maximum accuracy.
