In fact, the white gene hides the effect of any other color gene: it's epistatic! The fully white or white dominant ("W"), is dominant to the other alleles and to any other color gene. There are 3 possible alleles in this locus: W, ws, and w. The KIT gene is associated with the white color in many animals. The white and white spotting phenotypes are linked to the same locus W of the KIT gene.
Generally, cats with any amount of white are called by their base color plus “with white” when the amount of white is not specified. That’s why most odd-eyed cats are white or have white spots. When an eye is covered by a white patch, it may cause that eye to be blue.

If the cat’s nose or paws are covered by a patch of white, the leather color will be pink. In a way, you could say that white is an absence of color that “erases” the normal color of the cat. The rest of the cat coat can be of any of the color and pattern combinations that we have seen in the previous article. White spotted cats, also called piebald or bicolor, are simply cats with any quantity of white on them but that aren’t entirely white! The white spots can be limited to a locket on the chest or just some white mittens, up to an almost entirely white cat except for its ears and tail. The previous articles in the series covered: Note: Before reading this article, I recommend you read the first article in the series on solid cat colors, as some of the genetic explanations will be useful to understand this article. What's the color of your cat? To answer this question, in this fifth article in my series on cat coats I'm going to talk about white cats and piebald cats and explain everything about their genetics!
