How Gene Mutations Occur. Genes and chromosomes can be damaged in a number of different ways. They may be damaged directly, such as with radiation, or indirectly.

Male cats, with only one X chromosome, will have orange coats if they inherit the orange gene. Females, with two X chromosomes, need two copies of the gene to be fully orange, making them less common.

A unique mutation on the X chromosome in domestic cats causes orange coloration by activating the Arhgap36 gene in pigment cells, a mechanism not seen in other mammals.

Researchers found the gene and genetic variation behind orange fur in most domestic cats, solving a decades-long mystery. ... Calico and tortoiseshell cats also carry an X-chromosome mutation.

Typically, mutations that lead to yellow or orange fur in animals (and red hair in humans) occur within genes that control for color. And those genes aren’t carried on the X chromosome.
