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 of mackerels and sardines. In 2015 chub mackerels were found in Indian Ocean and the new species were classified as Scomber indicus. As larvae, chub mackerel feed mainly on copepods and rotifers and sometimes even smaller larvae of their own kind. Chub mackerel larvae can consume up to 87% of their dry body weight a day. As juveniles, chub mackerel feed mainly on zooplankton. As adults, they feed on mysids and euphausids. Spawning between chub mackerel typically occurs at temperatures of 59 to 68 °F. This in turn, leads to different mating seasons depending on what part of the hemisphere
