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
Atka mackerel on their fins. They have 21 spines, and anywhere from 25-29 rays on their dorsal fins, and only one spine (but 24-26 rays) on their anal fins. Found exclusively in the northern Pacific, Atka mackerel are known from Cape Navarin in the Bering sea, and from Stalemate and Bowers Bank in the Aleutian chain to Icy bay, Alaska. They can also be rarely seen as far south as Redondo Beach, California. Atka mackerel can generally be found from the intertidal zone to depths up to 575 meters. Atka mackerel migrate from shelves to coastal waters to spawn which occurs (in
