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 and include the butterfly mackerel, a species of primitive mackerel. Mackerel are strong swimmers. Atlantic mackerel can swim at a sustained speed of 0.98 metres/sec with a burst speed of 5.5 m/s, while chub mackerel can swim at a sustained speed of 0.92 m/s with a burst speed of 2.25 m/s. Most mackerel species have restricted distribution ranges. Three species of jack mackerels are found in coastal waters around New Zealand: the Australasian, Chilean and Pacific jack mackerels. They are mainly captured using purse seine nets, and are managed as a single stock that includes multiple species. Some mackerel species
