Hope everyone is having a Mellow Yellow Day! Today’s theme is going to be yellow cats. Yellow cats range in color from a dilute yellow to bright orange, (or almost red). These cats are sometimes called ‘Yellow Tabby Cats’, ‘Ginger’, ‘Marmalade’, and/or ‘Red Cats’.
Some interesting facts I found on the genes of cats:
The gene that causes the orange colour is unsurprisingly the sex linked “orange” (or sometimes called red) O gene. This gene is found on the X chromosome which means its inheritance is more complicated as males have one X chromosome and females have two. Therefore males have one O or o (recessive non red) allele, while females have two: OO, Oo tortoiseshell or oo (non-red).
Tortoiseshell cats are almost invariably female. The O gene creates an orange cat because it converts the pigment that makes a cat black, eumelanin into orange pigment phaeomelanin.
Yellow cats are a dilute orange and the dilution comes from the incorporation of the d gene into the genotype. However, it seems that an orange cat does not have to be dilute to be yellow. “Ginger” or “marmalade” are other terms for orange in the cat fancy.
