Why do white cats have odd-eyed eyes?

Further, it appears that only white cats seem to be odd-eyed cats. That’s because odd-eye cats almost always carry a dominate white hair gene1 (a gene that turns a cat completely white) or must possess a gene called the white spotting gene (makes a cat bicolor or tuxedo)2.
