The cross between a Roan Dark Brown stallion, whose coat the (Rn) gene acts on the base coat by distributing white hairs throughout the body, giving it a roan appearance. The head and legs retain the original base color tones. Dark brown coat, often nearly black, with black points, expressed over the bay base., and a Black mare with coat entirely black coat, with no dilutions and no Agouti gene action restricting black pigment to the points., can produce 8 different coat colors: Roan Bay (27%), Bay (27%), Roan Black (14%), Black (14%), Roan Chestnut (6%), Chestnut (6%), Roan Dark Brown (3%) and Dark Brown (3%). Results vary according to the genotype of each parent — use the filters above to explore specific combinations.
