FOIA Agouti husky has a rare coat color, darker than regular husky breeds. In most vertebrates, two key genes, Agouti and Melanocortin 1 receptor (Mc1r), encode a ligand-receptor system that controls pigment type-switching, but in domestic dogs, a third gene is im … Wild Type Black Banded Hairs (aw) Agouti signal peptide is also the gene that causes a wolf or coyote to have yellowish hair with black tips and base, or what is often called banded. The type of pigment synthesized in mammalian hair, yellow-red pheomelanin or black-brown eumelanin, depends on the interaction between Agouti protein and the Melanocortin 1 receptor. This is genetic.
