sequence analysis of three pigmentation genes in the newfoundland population of canis latrans links the golden retriever mc1r variant to white coat color in coyotes. | three genes, mc1r, agouti, and cbd103, interact in a type-switching process that controls much of the pigmentation variation observed in mammals. a deletion in the cbd103 gene is responsible for dominant black color in dogs, while the white-phased black bear ("spirit bear") of british columbia, canada, is the lightest documented color variant caused by a mutation in mc1r. rare all-white animals have recently been discovered in a new northeastern population of the coyote in insular newfoundland a ... | 2013 | 23297074 |
