text: It is these X chromosomes that carry the data that defines the coat colour of any given cat, and if a female cat carries one X chromosome for a ginger colour the other for a black colour, and lyonization occurs, which is a process by which one of the two colour expressions become inactivated in each of the two X chromosomes, the coat pattern that the cat displays will take on the signature patched or mixed calico or tortie pattern, which is known as mosaic expression.
