Genotype: Black Collared Splash
Phenotype: EE aa sw8sw1
Rarity: uncommon

Thoughts:
Since sw1 reduces the amount of white, the sw8 gene does not form a full collar.
In dogs, this gene is si, and Ssi would create the same effect, whereas sisi would be a full collar.
I assumed this gene likely would follow that when combined with a white gene with lesser effect, correct me if I am wrong!
