Piebald - Piebald is a recessive trait that is partially un-pigmented with variable color and pattern mutations.  Piebalds express an unusual cloud-like pattern unseen in any other base-morph. The amount of white is not indicative of its parents’ color.  For instance, a 90% white piebald bred with a 90% piebald, may not produce 90% white offspring.  The amount of white is typically a random occurrence.  Pieds are a color and pattern mutation with an aberrant body pattern while the head is typically normal looking. Although some have confused ringers with pieds, there are some distinct differences.
