Real world is seen through a bayesian framework
The chances of a tri-color gene expressed in tomcats is small as the chromosome set must be abnormal. The rarity of male calico (the incidence of human 47,XXY, Klinefelter syndrome, is around 1/800 male births) have been well-known in Japan for a long time and this is the reason why most calico Maneki Nekos are considered as a lucky charm and especially revered as the lucky cat by sailors all over the world.
As the orange gene is on the X chromosome and male cats have only one X chromosome, tomcats are either orange or black. Heterozygous females are mosaics of orange and nonorange fur due to X-inactivation.
Maneki Neko in the first page of a site about chance and risk calculation attracts visitors. The patch size of the mosaic correlates with the size of the white spots produced by the piebald spotting locus. The patch size of the mosaic correlates with the size of the white spots produced by the piebald spotting. In one-week embryos, one of each X chromosomes is randomly silenced creating a cat with patches of coat color.
