Other self white cats are the result of extreme expression of the white spotting gene discussed later. The cat may be genetically black, genetically cream etc, but the presence of the white gene obscures the colour. Self white (not shown) masks any underlying colour. The red-based colours are genetically solid, but because of the way the red pigment and non-agouti gene interact, they may have discernible tabby markings. There are 9 eumelanin-based (black-based) self colours and 3 phaeomelanin-based (red-based) self colours. For seen-once mutations, use the location where it was observed (e.g. Use descriptive plain English (swirled, skunk-stripe) ORĥ. Borrow terminology from other livestock (e.g. Use the breed developer’s terminology (e.g. I’ve used this order of precedence for naming conventions:Ģ. Depicting my own content pictorially is not plagiarism as alleged by said individual, but is a legitimate use of my own collated data presented in standard textbook format. Note: I’m aware that Messybeast information, including novel terminology, was reproduced by deviantart’s “cedarseed” without attribution and that hir successor, “majnouna”, objects to me creating my own charts from my own information. Please credit the source if you reproduce the contents because as well as material from cat breed standards and genetics texts, the charts depict material from my own studies which are described (with photos) elsewhere on. The explanatory text and the charts are in the public domain for breeders and can be edited as required for your own breed. This page may load slowly due to the number of downloadable images. There are also charts of 2 sought-after patterns that haven't been confirmed in cats. In several cases, I've taken the liberty of coining terms for certain patterns for ease of describing something not formally described by a cat fancy standard (some of these terms have since been used by other people creating their own charts from my information). The eumelanin (black) series and the phaeomelanin (red) series are alongside for comparison. Below that are the two dilution modifiers. The charts are laid out in the normal 2-axis format seen in textbooks: the most dominant allele is at the left (black) and in descending order of dominance to the most recessive allele on the right (cinnamon). Any genetics contents is extremely simplified! Similar color charts have appeared in Wright & Walters (The Book of the Cat, 1980) and in Robinson's Genetics (1977 onwards) and I've updated those with recent developments and made them freely available. This page doesn't go into inheritance genetics in depth, but is intended to depict the range of colours and patterns. The charts on this page can be downloaded (right click and "save as") full size for use in breed tutorials and web-pages.
