LWO/OLWS-positive  = a carrier of the Lethal White Overo gene (LWO/OLWS); expected to pass it on to 50% of the offspring; Caution: mating with another LWO carrier has a 25% calculated risk of producing a lethal white foal according to UC Davis.

E/E = Homozygous Black. He will pass a black gene to 100% of his babies.

a/a = two copies of the recessive non-agouti “a”; this allele does not restrict the black hair in EE or Ee horses, and the base color is black; no visible color effect in an “e/e” (red-based) horse.
