Patches are pattern language
The Cat Fanciers Association treats tortoiseshell and calico as pattern descriptions, not breeds. Its examples distinguish mixed red and dark-color areas from patterns that also have substantial white. This guide does not identify a cats chromosomes, fertility or sex from those visible areas.

A point is an arrangement
The association describes pointed coats as darker color at extremities such as face, ears, feet and tail. It warns that not every pointed cat is Siamese. A description can use the arrangement without making an ancestry claim or treating an online photograph as a breed test.

Genetics explains, but does not certify
UC Davis describes colorpoint restriction and temperature-sensitive alleles in its coat-color overview. That general mechanism is not an individual DNA result. This site does not identify a variant or calculate inheritance probabilities from the colors of one or two cats.

No breeding recommendation
The guide offers no mating plan, litter prediction, purchase ranking or rarity price. Describing a coat is a different task from assessing health, ancestry or responsible breeding. Those questions require their own evidence and qualified advice, not a color-word worksheet.
