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
Mackerel scad western Indian, and the North west, center west, center east and south west Pacific. Mackerel scad usually live in subtropical seas at depths up to 400 m. They prefer clear water, and are frequently found around islands. Although mackerel scad have been found at the surface, they are usually caught at depths between 40 and 200 meters. They feed mainly on zooplankton. Mackerel scad are fairly important both to fisheries and to sportfishing. They can be used as food, but are known to carry ciguatera, and are more often used as bait, since large gamefish such as the blue-spotted grouper,
