The orange mutant gene is found only on the X, or female, chromosome. As with humans, female cats have paired sex chromosomes, XX, and male cats have XY sex chromosomes. The female cat, therefore, can have the orange mutant gene on one X chromosome and the gene for a black coat on the other. The piebald gene is on a different chromosome.

Male cats, like males of other therian mammals, are heterogametic (XY). [19] The single X chromosome does not undergo X-inactivation, ergo coat color is determined by which O-gene allele is present. Accordingly, the cat's coat will be either entirely orange or melanistic (respectively X O Y or X o Y).
This is why most orange cats are male (one copy of the orange gene from their mother on the X chromosome) but nearly all tricolor cats (calico) or tortoiseshell cats (black and orange) are female ...
