Judging a salmon by its spots: Environmental variation is the primary determinant of spot patterns in Salmo salar
In fish, morphological colour changes occur from variations in pigment concentrations and in the morphology, density, and distribution of chromatophores in the skin. However, the underlying mechanisms remain unresolved in most species. Here, we describe the first investigation into the genetic and e...
