Dogs have about 19,000 genes in their genome [2] but only a handful affect the physical variations in their coats. Most genes come in pairs, one ...
The project took samples from 38 different breeds to find the gene (a beta defensin gene) responsible for dog coat color. One version produces yellow dogs, and a mutation produces black.
