Are all orange cats male?

Many of us have noticed that he majority of orange cats are male, but why? Well, the gene for the orange color is on the X chromosome. Since males have only one X, so will either be orange or not. Females have two X chromosomes, so can have another color on one of the X's, winding up with a non solid orange female cat. In other words, an orange female cat must have both an orange father and either an orange or calico mother, whereas an orange male only needs one parent to be orange or calico.
