Tabby cat or "hypermelanistic" allele, "a", does not. Solid-color (black or blue) cats have the "aa" combination, hiding the tabby pattern, although sometimes a suggestion of the underlying pattern can be seen (called "ghost striping") This pattern is mostly seen in young cats that still have the baby coat. The right pattern (Classic, Mackerel, or Spotted) will reveal itself then, because that is independent of whether it is tabby or solid. However, the agouti gene only controls the production of black pigment, so a cat with an "O" allele for orange color will still have the tabby pattern. As a result, both
Cat body-type mutation from Treker's dominant mutation. Most teacup and toy size Persian kittens raised now are descendants from Silver and Golden color division to reduce cat size and are in no way related to Treker. Cat body-type mutation Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these cat body-type mutations are striking enough that humans select for and perpetuate them. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. This page gives a selection of cat body type mutant
