Red Coat Colour Test for Cats (Orange / Tortoiseshell / Calico)
The distinctive red coat colour in cats is determined by a genetic variant of the Arhgap36 gene, located on the X chromosome. This variant is inherited in a sex-linked manner and affects pigmentation by suppressing the black-brown pigment eumelanin and enhancing the orange pigment pheomelanin.
- Male Cats: As males have only one X chromosome, they will display a red coat if they inherit the red variant (X(O)/Y). Without this variant (X(o)/Y), they will not have a red coat.
- Female Cats: Females possess two X chromosomes and require two copies of the red variant (X(O)/X(O)) for their coat to be completely red. If only one X chromosome carries the red variant (X(O)/X(o)), random X chromosome inactivation results in a combination of red and non-red areas, producing the beautiful tortoiseshell or calico patterns. Cats with the genotype (X(o)/X(o)) will not display the red coat colour.
This test provides valuable insights into the inheritance of red coat colour, assisting breeders in understanding and predicting coat patterns in their litters.
