The earlier theories are still worth summarising.Ībitbol, M., Dargar, T. Ultimately, detailed pedigree analysis revealed an autosomal recessive inheritance pattern for the “British recessive wideband” (wb BSH) gene. Leslie Lyons of the Lyons Feline Genetics Laboratory has been researching silver and golden for a number of years without identifying a gene the emergence of the flaxen gold and extreme chinchilla phenotypes may prove fresh impetus for research and new genetic variations for study. In the meantime, several theories were put forward based on known mutations and genes, some more plausible than others. At the same time, DNA was collected for analysis from cats with the new phenotype. Initial investigations, starting in 2016, were based on known mutations and on pedigree analysis. Until “flaxen gold” (WCF term) is officially recognised with its own code, these cats can’t compete in the golden class against classic goldens. Different coding on the pedigree keeps the new colour separate from the original golden colour so breeders can decide whether or not to use a copper/flaxen gold cat in their golden programmes. Because it involves the CORIN gene it is also called 'CORIN gold.'įrom 1st March 2021, associations affiliated with WCF had to segregate the standard golden kittens from the copper/flaxen gold (extreme golden) kittens which have pale bellies and white feet. Fans of the colour saw it as a natural evolution of colour to create the perfect golden cat. The bleached (or “excessive”) version was termed 'flaxen gold' by WCF and the light gold (colour of set honey) is also called 'British Sunshine' by some breeders but is not the same as the Siberian sunshine mutation. Some cats were pale yellowish gold with nearly-white toes. This was known as 'akita' or 'urajiro' by Russian breeders and 'copper' elsewhere. Breeders, particularly in Russia, continued to select the brightest gold chinchillas to breed with and the brightest, most orange, golden cats had pale toes and pale markings around the eyes as well as an ivory belly. In adulthood the ticked-based goldens and silvers had extremely uniform tipping with no hint of a tabby pattern. The new goldens (and related new silvers) British Shorthairs/Longhairs that appeared in Europe were not ny11 (tabby-based goldens), but were ny25 (ticked-based goldens) and attracted a lot of interest in Russia. Refer to Wide Band: History of the 'New' Colours 'Golden Copper' and 'Golden Akita' in the British Breed how does it affect non-ticked cats? It seems to turn the markings to gold and the only evidence of the black marking colour is seen at the tail tip and on the paw pads.ĮMERGENCE OF COPPER/FLAXEN GOLD IN RUSSIA The naming is not yet decided.Īlthough the true Copper/Flaxen Gold phenotype involves tipping/ticking, what do tabby-marked related cats look like? i.e. Breeders sought recognition for this colour as 'Light Gold,' but the term 'Flaxen Gold' was preferred by WCF. These phenotype deviates from the standard for tipped cats but became widespread in Russia and in some German lines of British Golden Shorthairs.

black or blue) restricted to the tail tip and an absence of dark nose-liner. The term 'copper' (now known as Flaxen Gold by WCF) was adopted by Linda Petersson Wahlqvist to describe Golden Shell cats with white toes, white undersides, golden colour with the dark tips (e.g. It looked like an 'ultra wide-band' effect where the colour was pushed so far to the tips of the hairs that the genetic colour (black, blue, chocolate etc) was barely discernible and the paler areas were a very extreme golden colour that was almost white. In the early 21st century a new type of “golden” appeared in Tipped and Shaded Golden (Golden Chinchilla and Golden Shell) British Shorthairs. In 2022 it was identified as a CORIN gene mutation.Ĭopper = akita/urajiro = light gold = flaxen gold = British sunshine = CORIN gold (there are multiple names for this mutation in British Shorthairs/Longhairs)
