How the Calico is Created
- A cat needs two X chromosomes to present with the tri-color calico pattern.
- If a cat has an XX pair of chromosomes, it will be female.
- Male cats have an XY chromosome pair, so they can rarely be Calicos.
There are 3 well known types of calico cats: Dilute, Tortoiseshell, and Patched Tabby. Each of these three calico cats differ in color. Dilute means that the colors are less intense, hence “dilute.” However, the Tortoiseshell and Patched Tabby types do feature unique differences in color.
