Eliminating Mutations – The Impossible Dream

Though it is not practical to eliminate all deleterious mutation, the incidence of affected individuals may be significantly reduced through a combination of intelligent breeding practice and the development of DNA tests. Why do we have mutations? Mutations are changes in an organism’s DNA that potentially affect the correct functioning of genes. They occur naturally […]

The Effects of Genetic Testing: Constructive or Destructive?

Every breed has genetic disorders. Finding tests that identify carriers of the genes which cause these disorders is a goal in all breeds. Once a genetic test is found, however, it is a double-edged sword: Its use can enable breeders to improve a breed or devastate it. Without genetic tests, the number of dogs that […]
