"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.

Chub mackerel of mackerels and sardines. In 2015 chub mackerels were found in Indian Ocean and the new species were classified as Scomber indicus. As larvae, chub mackerel feed mainly on copepods and rotifers and sometimes even smaller larvae of their own kind. Chub mackerel larvae can consume up to 87% of their dry body weight a day. As juveniles, chub mackerel feed mainly on zooplankton. As adults, they feed on mysids and euphausids. Spawning between chub mackerel typically occurs at temperatures of 59 to 68 °F. This in turn, leads to different mating seasons depending on what part of the hemisphere
