I

I locus — silver & smoke

Controls: Whether the hair has a silver-white base (silver, smoke, chinchilla).

How it works

The dominant Inhibitor gene (I) removes pigment from the base of each hair, leaving a silver-white undercoat. On a tabby it gives silver; on a solid it gives smoke; with heavy tipping it gives shaded or chinchilla.
