The coat colour red is caused by a genetic variant of the Arhgap36 gene, which is located on the X chromosome and is therefore inherited in a sex-linked manner<\/strong>. The variant leads to a suppression of the production of the black-brown pigment eumelanin and promotion of the orange pigment pheomelanin<\/strong>.
As male cats only have one X chromosome<\/strong>, their coat colour is red if the red variant O is present<\/strong> (genotype X(O)\/Y). If the variant is not present, they are not red (genotype X(o)\/Y).
Female cats have two X chromosomes<\/strong> and need two copies of the red variant<\/strong> (genotype X(O)\/X(O)) to show completely red fur. If the red variant is only present on one of the two X chromosomes<\/strong> (genotype X(O)\/X(o)), red and non-red areas of the coat<\/strong> will be expressed due to random X inactivation, resulting in a tortoiseshell or calico pattern. With the X(o)\/X(o) genotype, a cat does not show the coat colour red.<\/p>Method<\/strong><\/td> Heredity<\/strong><\/td> Duration<\/strong><\/td>
