Genetic basis
Extension E/-, Agouti a/a, Pearl nPrl — Pearl has near-zero visible effect on a black base.
The Dun gene dilutes the base coat and adds primitive wild-horse markings: a dorsal stripe along the spine, leg barring, and sometimes shoulder stripes.
The Frame Overo pattern adds irregular white patches to the base coat. Crossing two Frame horses is dangerous: 25% of foals will be homozygous O/O (OLWS) and will not survive.
