Color linked genes

I believe there are performance genes linked to the color genes " in some strains" but not in general. Some of the maltese Plotts are pretty, there have historically been some outstanding ones. Personally I do not favor them due to the dilute gene hampering the pigment, I don't like a lack of pigment. I wouldn't be concerned with a buckskin Pott as long as they had a black nose.
Same with the red muzzled red nosed BMC's. In the Leopard breed I am leary of a white headed blue eyed dog. Long story short in nature a lack of pigment is generally a weakness.
With that said, I don't know of the Lacy breed having any issues with the blue color or the yellow red nosed ones. Nor the red nosed BMC's and very few maltese Plotts.
Then we get into the "pattern or marking" genes. Solid, Brindled, Merle, Blanket or saddle backed with or without white, open spotted. I figure that would all be just personal preference.
At the moment I don't own a Plott of my favorite color " black with brindle head and legs or saddle backed" but color is way down on my list.
