The king cheetah is a rare mutation of the cheetah characterized by a distinct fur pattern. The cause of this alternative coat pattern was found to be a mutation in the gene for transmembrane aminopeptidase Q, the same gene responsible for the striped ‘mackerel’ versus blotchy ‘classic’ patterning seen in tabby cats. The mutation is recessive and must be inherited from both parents for this pattern to appear, which is one reason why it is so rare.
