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 classic tabby is most common in Iran, Great Britain and in lands that were once part of the British Empire and Persian Empire. The gene responsible for this differential patterning has been identified
Atlantic mackerel according to the IUCN, "highly uncertain." Atlantic mackerel outer meat is red meat while inner meat is white, with a strong taste desirable to some consumers. They are sold fresh, frozen, smoked, salted, filleted, or as steaks. The fish is extremely high in oil content, vitamin B, vitamin B, selenium, niacin, and omega 3, a class of fatty acids, containing nearly twice as much of the latter per unit weight as salmon. Unlike the King and Spanish species, Northern Atlantic mackerel are very low in mercury, and can be eaten at least twice a week according to United States Environmental
