Tabby cat red cats and the patches of red on tortoiseshell cats will show tabby striping. The primary tabby pattern gene, "Mc/mc or Mc/Mc", sets the basic pattern of stripes that underlies the coat. "Mc" is the wild-type tabby gene and produces what is called a Mackerel Striped tabby. Classic tabbies are cats who also possess "mc/mc", a recessive mutant gene that produces the blotched pattern. The spotted gene is directly connected to the Mc gene; it 'breaks' the lines of a Mackerel tabby, turning it into spots. The spotted gene is dominant as well, which means a Spotted will be Sp/sp
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
