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
Chub mackerel Chub mackerel The chub mackerel, Pacific mackerel, or Pacific chub mackerel ("Scomber japonicus") is a species of fish in the tuna and mackerel family, Scombridae. This species of mackerel closely resembles the Atlantic chub mackerel. The chub mackerel has a well-developed swim bladder attached with the esophagus, which the "true mackerels" in the genus "Scomber" lack, and a characteristic color difference is seen between the chub and the Atlantic chub, the latter being silvery-sided below the midline, whereas the lower part of the sides of the chub (otherwise colored somewhat like the Atlantic) are mottled with small dusky blotches, and
