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
Chub mackerel the closely related Atlantic chub mackerel in the Atlantic. The chub mackerel is widely distributed, usually found in the northwestern, southeastern, and northeastern Pacific. In the eastern Pacific, it can be found from central Mexico to southeastern Alaska. Chub mackerel are generally found within 20 miles (37 km) off the coast in waters between 50 and 72 °F (10 to 22 °C). Young mackerel live around sandy beaches or kelp beds, while adults are found in deeper waters in shallow banks to 1000 feet (300 m) deep. Chub mackerel school with other pelagic species, as well such as other types
