ROAN

Roan is a tricky gene! It does not change the texture of the coat, only the color; but it can act on any color of rat.

​

Roan rats are born their true color with a white blaze. Over time, their natural color is replaced with more and more white hair. Some roan rats will turn completely white, especially lighter ones.
