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
Savannah cat the Chausie and Bengal cat, most first generation cats will possess many or all of the serval's exotic looking traits, while these traits often diminish in later generations. Male Savannahs tend to be larger than females. Early-generation Savannahs can weigh , with the most weight usually attributed to the F1 or F2 neutered males due to genetics. Later-generation Savannahs are usually between . Because of the random factors in Savannah genetics, size can vary significantly, even in one litter. The coat of a Savannah should have a spotted pattern, the only pattern accepted by the TICA breed standard. The spotted
