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
King mackerel evident. Atlantic Spanish mackerel have prominent yellow spots on the flanks at all sizes. In addition to such spots, cero have one or more yellow stripes along the centerline. Young king mackerel have similar, but slightly smaller spots, these fade away on individuals weighing over , but may still be seen as slightly darker green spots toward the back from some angles of view. Worldwide, many fish of these three species are quite similar to one or another. Off Mexico, Atlantic Spanish mackerel may be confused with Serra Spanish mackerel, "Scomberomorus brasiliensis".
