"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
