A new study has found that there are five distinct coat colors in dogs and wolves. Previously scientists believed that there were only four. The mystery of coat colors has been solved. (However, we never know what discoveries the future holds.)
This discovery is the result of the work done by an international team of researchers including scientists from the Institute of Genetics of the University of Bern. The team found that a genetic variant which is responsible for a very light-colored coat in dogs and wolves originated in a now extinct relative of the modern wolf.
According to the research a small piece of DNA from this extinct ancestor is still found in yellow dogs and white artic wolves.
Note: This information may help breeders better determine the potential coat color of future litters. I hope that it eventually helps eliminate the deafness and other ills that are connected to certain colorations in dogs, namely the merle, harlequin, piebald and for some breeds the all-white factors, that cause genetic problems.)
