Cat coat genetics basic pattern of stripes that underlies the coat. The basic wild-type tabby gene, "Mc", produces what is called a "mackerel striped" tabby (stripes look like thin fishbones and may break up into bars or spots), while a recessive mutant, "mc", produces a blotched or "classic" tabby pattern (broad bands, whorls, and spirals of dark color on pale background usually with bulls-eye or oyster pattern on flank).

The gene responsible for this differential patterning has been identified
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
