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.

However, the orange cats were missing a stretch of DNA that could be involved in regulating how much protein the cell produced. And, after scanning a database of 188 cat genomes.
Calico cats are almost always female, due to the way that coat colors work on cats. The genes determining whether a cat has an orange or black coat are located on the X chromosome, and exhibit co ...
The colors are often described as red and black, but the "red" patches can instead be orange, yellow, or cream, [2] and the "black" can instead be chocolate, gray, tabby, or blue. [2] Tortoiseshell cats with the tabby pattern as one of their colors are sometimes referred to as torbies or torbie cats. [7]
The term designer cat is often used to refer to these cat breeds. [1] This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. To protect the animal’s welfare it is illegal in several countries or states to breed with parent cats that bear certain of these ...
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 ...
The orange tabby, also commonly called red or ginger tabby, is a color-variant of the above patterns, having pheomelanin (O allele) instead of eumelanin (o allele). Though generally a mix of orange and white, the ratio between fur color varies, from a few orange spots on the back of a white cat to a completely orange coloring with no white at all.
