Presentation with Contradicting Mutations:
Albinism and Melanism:
Albinism and Melanism presenting together cancel out Albinism's skin/eye/marking color requirements.
When Albinism and Melanism are both present in a geno, any of the following approaches can be taken:
-One mutation presents visibly, and one is a genetic carrier only. (At least one mutation has to present visibly in this case.)
-Albinism presents darker/subtler than average:
Sunbeam base.
-Melanism presents lighter/subtler than average:
Sunbeam base.
-Both Albinism and Melanism appear, in cloudy patches:
Sunbeam base.
The edges of this must be soft and blended so as to not be confused for Tortoiseshell, Chimera, or other similar markings/mutations.
