Southeast African cheetah of this alternative coat pattern was found to be a mutation in the gene for transmembrane aminopeptidase Q ("Taqpep"), the same gene responsible for the striped "mackerel" versus blotched "classic" patterning seen in tabby cats. The cheetah also has melanism as one of its rare color morphs. A melanistic cheetah in Zambia was seen by Vesey Fitzgerald in the company of a spotted cheetah. The cheetah is a medium-sized cat.
