![]() Male cats have only one X gene, paired with a Y gene to determine sex. An Orange male cat must its gene as ‘O’.īecause X-inactivation allows each gene to be visible in various regions on the cat, a completely Orange cat must have both genes as ‘O’. If the cat shows no sign of dilution, then fill these in on your table: Locus If the cat shows dilution, then fill these in on your table: Locusĭense coloring is dominant over dilution. Both parents must contribute a dilute gene to have it take effect. If your cat does not show the effects of these genes, follow this link:įill in the no Inhibitor/Wideband Gene Table… Gene Tablesĭiluted coloring is recessive. The breeders then select for high rufousing, which produces a genetically black cat that is a golden color. So the “background” color remains over most of the fur. These cats have the Wideband gene but not the Inhibitor gene. If the color is just on the tip of the hairs, it is a Silver Chinchilla. The paw pads are black and the lips are too, showing that genetically this is a black cat under all the modification. The Inhibitor gene is also active and makes all the rest of the hair white. In these cats, the Wideband gene is active and pushes the color out to nearly the tip of the hair. The base of each hair is whitened, even under the stripes.įill in the Smoke and Silver Tabby Gene Table… If the cat is a solid, a “Smoke” is formed. If the cat is a tabby, this results in a silver tabby. So the pattern is in the normal place on the hair, but the background tint is entirely white – giving a silvery look. These cats have the Inhibitor gene, but not the Wideband gene. They are less common due to the relative lack of contrast between the Orange and White. There are Orange versions of these cats, called “Cameos”. Wideband moves the colored portion of the hair outward to the tip, leaving more background visible. This leaves the base of each hair white instead of a pale version of the main color or the brown-orange rufousing color on agouti hairs. Inhibitor blocks the ‘background’ pigment entirely, leaving it white. Two genes, Inhibitor and Wideband, modify how the pigment controlled by all the other genes is laid out on each hair. Shaded, Smoke, Chinchilla, Silver and Golden Cats Sadly, you can’t tell what it is without additional information. If your cat shows no black, it still has a black gene that children can inherit. ![]() The grains are nearly round in the Black, and more oblong for Chocolate and Cinnamon.Ĭhocolate and Cinnamon are rare, so be sure that you are taking into account the all of the modifiers that can change the way a full black cat looks, such as the pointing genes and dilute, before deciding you have one of these options. These correspond not to a difference in pigment, but in how it is deposited on the hair. There are three different options for the black gene. Tortie and Calico cats are predominately female. There are different options if you cat is male or female…įill in the non-Orange Female Gene Table… ![]() If your cat does not have diluted colors, and seems to have the full intensity colors, you can fill the dilute gene table to show that dilution is not in effect. If your cat matches these colors, then the dilute gene is active. The pictures below give an example of the dilute counterpart for the basic cat colors.
