Genotype options:
Roan causes the coat on the body to have evenly mixed white and colored hairs, resulting in the coat looking like it's been airbrushed by semi-opaque white while leaving the legs and face unaffected. The amount of white hairs varies between each horse, as well as the "even-ness" - it can appear slightly varnished or textured.
Roan can optionally affect the mane and tail where it touches.
At minimal expression roan needs to have subtle roaning starting around the rear.
Minimum requirements can be reduced or completely removed by the occlusion trait.
Doesn't affect eye colour.
Doesn't affect skin colour.
Doesn't affect horn or hoof colour.
The minimum requirements of Roan must still be met regardless if Corn spots is shown or not.
Corn spots is not listed in the phenotype, a Roan with Corn spots is still only written as Roan.
Corn spots on roan causes small "holes" in the roaning where the base coat is visible. Corn spots should always be fairly small (anywhere between tiny speck to as large as the eye), and can be round or slightly uneven in shape as long as it looks like spots.
Doesn't affect eye colour.
Doesn't affect skin colour.
Doesn't affect horn or hoof colour.
The minimum requirements of Roan must still be met regardless if Reverse dapples is shown or not.
Reverse dapples is not listed in the phenotype, a Roan with Reverse dapples is still only written as Roan.
Roan can have a reversed dapple effect, with dark dapple spots on the roaned areas. These dapples can be anywhere from just subtly darker, to completely showing the basecoat underneath. A roan with heavy dapple effect can appear as white lacing on the coat, as shown on the third example.
Doesn't affect eye colour.
Doesn't affect skin colour.
Doesn't affect horn or hoof colour.
