Traits

Not to be confused with dapples, or roan that can lead to dark hairs when there's a small injury, Bend-Or spots (also known as Ben d'Or, Smuts and Grease Spots), they are dark spots that appear mostly on chestnuts, palominos, and darker reindeer no matter their age.  These are also quite rare and can be so dark that it looks black, but usually they are slightly darker than the coat base color. 

Vitiligo is a skin depigmentation, though may be harder to see on white or "off-white" reindeer.

For sabino only, these spots make one side or the flank look like a spotted reindeer.

Mismarked Spots only happen for the spotted gene in reindeer, where the spots disappear in certain areas of the coat to show the base coat, nearly mistaking it for a Chimera.  However, this anomaly doesn't pass down to calves..
