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
Atka mackerel the Aleutians) from July to September. Their eggs adhere to crevices in the rocks, and incubate for 40–45 days. Males guard the clutches of eggs until they hatch. Atka mackerel feed on copepods and euphausiids. They are, in turn, preyed upon by several species, such as the coho salmon and the Steller sea lion. Atka mackerel are used as food in the Aleutian chain, and can be caught as game fish. American ichthyologist David Starr Jordan wrote about fishing for Atka mackerel on May 28, 1892 in "American Food and Game Fishes": Atka mackerel The Atka mackerel ("Pleurogrammus monopterygius") is
