A tortoiseshell cat is a feline with a distinctive coat pattern characterized by a mottled or patchy combination of black, red, and orange fur, often with white. This pattern is named after the tortoiseshell material, which has a similar appearance. Tortoiseshell cats are often affectionately referred to as "torties."
Genetics
The unique coloration of tortoiseshell cats is due to a genetic phenomenon known as X-inactivation. The gene responsible for the orange color is located on the X chromosome. Since females have two X chromosomes, they can express both black and orange colors, resulting in the tortoiseshell pattern. Male tortoiseshell cats are rare and usually sterile, as they typically have an extra X chromosome (XXY), a condition known as Klinefelter syndrome.
Characteristics
