Male cats, just like male humans, have an X and Y chromosome. So any male cat with this mutation ends up orange. Female cats need the mutation on both of their X chromosomes to be fully orange, which is statistically less likely. So nearly all calico and tortoiseshell cats are female because this mutation is found on only one of their X chromosomes.
