The genetic basis of melanism in the gray squirrel (Sciurus carolinensis).
The black squirrel is a melanic variant of the gray squirrel (Sciurus carolinensis). We found 3 coat color variants in the gray squirrel: the wild-type gray, a jet-black, and a brown-black phenotype.Expand
Melanocortin 1 receptor (MC1R) gene sequence variation and melanism in the gray (Sciurus carolinensis), fox (Sciurus niger), and red (Sciurus vulgaris) squirrel.
Sequence variations in the melanocortin 1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds, and reptiles. The gray squirrel (Sciurus carolinensis), foundExpand
Agouti signalling protein is an inverse agonist to the wildtype and agonist to the melanic variant of the melanocortin‐1 receptor in the grey squirrel (Sciurus carolinensis)
The melanocortin‐1 receptor (MC1R) is a key regulator of mammalian pigmentation. Melanism in the grey squirrel is associated with an eight amino acid deletion in the mutant melanocortin‐1 receptorExpand
Multiple origins of melanism in two species of North American tree squirrel (Sciurus)
BackgroundWhile our understanding of the genetic basis of convergent evolution has improved there are still many uncertainties. Here we investigate the repeated evolution of dark colourationExpand
The genetic and molecular basis of melanism in the grey squirrel (sciurus carolinensis)
The grey squirrel (Sciurus carolinensis) has wildtype and melanic (dark) colour morphs. Melanism is associated with variations in the melanocortin-1 receptor (MC1R) gene in a number of species. TheExpand

Sequence variations in the melanocortin-1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds and reptiles. The grey squirrel (Sciurus carolinensis), foundExpand
