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 we have 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 that the only natural CP cat is the Siamese.  We also bring silver that is a natural mutation in forest cats such as Siberians and finally the classic pattern which is an ancient tabby mutation and totally normal in Siberians.

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

Abour silver:

Damman Amur Lucy, Group 2, black silver spotted tabby

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 any other publications and it is certain that silver is natural mutation that appeared EXACLY in forest cats to start.
Extract from Roy Robinson’s book and Lyons Feline genetic Laboratory web site.
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 give a contribution.  I am sending my Homozygote silvers.

About 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”.
Classic pattern was already present among the domestic cat population that mixed with Felis Silvestris Caucasia, originated the Siberian cat.
Any mention that classic pattern is a foreign pattern to Siberians is pure non sense but a very used allegation repeated by nem mixers who simply repeat non sense “they heard”.
