Traits

This form of mutation occurs most commonly as black patches on a red base, but can occur as any patch of unexpected color. Generally these mutations are smaller and in a few areas, or one slightly larger spot on the coat. An extreme form of somatic mutations could be mosaicism, resulting in large patches across a dog's coat - this is much rarer.

For dogs with somatic, they will have a 25% chance of passing on the mutation (50% if both parents are somatic). If a puppy rolls for somatic, they will also have a 10% chance of becoming mosaic unless the parent(s) are also mosaic.
