![]() O is dominant over black (non-orange), so if a male has the O gene, he will be ginger. ![]() Male tortie or calico cats do exist (the incidence is 1/3000) due to an extra X chromosome which makes them XXY, however, they are almost always infertile. Regardless, Manny will live a long and happy life. As the male (XY) only has one X chromosome he will be orange or non-orange. We would need to do further testing called karyotyping to find out what which type Manny is. For example, one zygote had a black coat color and the other an orange.

Since female cats have two X chromosomes, they can be solid black, solid orange or both black and orange. The X chromosome codes for the coat colors – orange/red and black.
