[12Quagga]

Kinda skipped ahead a bit, this boy started out as a normal horse and I was doing tobino and it just went from there

Genotype: Ee/Aa/RIRI (Ring that's what I'm calling this marking)
Phenotype: Bay with ring

So anyways my idea was ring acts similar to paint markings and can range from a small ring of white or any other color around the chest to larger bands, it's very unpredictable and when combined with other markings can yield unexpected results. Bold white facial markings/stockings/ white inner ears as well as a white mane and tail tuff are signs of carriers and the white flecking is a sign of a homo.
