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 Spanish mackerel without overfishing occurring. Spanish mackerel are primarily marketed fresh or frozen as fillets as commercially caught fish are too small to sell in the form of steaks. Their raw flesh is white. They may be prepared by broiling, frying, baking or, rarely, by smoking. The Spanish mackerel is also a popular sushi fish. By analogy with the Japanese Spanish mackerel, which is a member of the same genus, it is often called "sawara" on sushi menus. Spanish mackerel are similar in appearance to small King mackerel ("Scomberomorus cavalla") and Cero mackerel ("Scomberomorus regalis"). All three are very similar in shape
