Tabby cat red cats and the patches of red on tortoiseshell cats will show tabby striping. The primary tabby pattern gene, "Mc/mc or Mc/Mc", sets the basic pattern of stripes that underlies the coat. "Mc" is the wild-type tabby gene and produces what is called a Mackerel Striped tabby. Classic tabbies are cats who also possess "mc/mc", a recessive mutant gene that produces the blotched pattern. The spotted gene is directly connected to the Mc gene; it 'breaks' the lines of a Mackerel tabby, turning it into spots. The spotted gene is dominant as well, which means a Spotted will be Sp/sp
Chub mackerel Chub mackerel The chub mackerel, Pacific mackerel, or Pacific chub mackerel ("Scomber japonicus") is a species of fish in the tuna and mackerel family, Scombridae. This species of mackerel closely resembles the Atlantic chub mackerel. The chub mackerel has a well-developed swim bladder attached with the esophagus, which the "true mackerels" in the genus "Scomber" lack, and a characteristic color difference is seen between the chub and the Atlantic chub, the latter being silvery-sided below the midline, whereas the lower part of the sides of the chub (otherwise colored somewhat like the Atlantic) are mottled with small dusky blotches, and
