Scientists in the US and Europe are making progress in identifying the genetic mutations that cause inherited illnesses, developing tests for themand mapping the dog genome. Canine genetics research is beginning to make important contributions to the understanding of human genetic disorders.cientists in the US and Europe are making progress in identifying the genetic mutations that cause inherited illnesses, developing tests for themand mapping the dog genome.
