Cat coat genetics as "transmembrane aminopeptidase Q" ("Taqpep"), which also produces the king cheetah coat variant. Spotted tabbies have their stripes broken up into spots, which may be arranged vertically or horizontally. A 2010 study suggests that spotted is caused by the modification of mackerel stripes, and may cause varying phenotypes such as "broken mackerel" tabbies via multiple loci. The "Ticked" gene, "T / t", produces an "Abyssinian ticked" or non-patterned agouti tabby with the dominant allele, having virtually no stripes or bars. Stripes usually remain to some extent on the face, tail, legs, and sometimes the chest. The dominant ticked tabby allele
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
