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
Mackerel scad western Indian, and the North west, center west, center east and south west Pacific. Mackerel scad usually live in subtropical seas at depths up to 400 m. They prefer clear water, and are frequently found around islands. Although mackerel scad have been found at the surface, they are usually caught at depths between 40 and 200 meters. They feed mainly on zooplankton. Mackerel scad are fairly important both to fisheries and to sportfishing. They can be used as food, but are known to carry ciguatera, and are more often used as bait, since large gamefish such as the blue-spotted grouper,
