Inbreeding of dogs
Inbreeding is a way for males and females who are closely related to each other to mate and reproduce. That is, the mating between father, daughter, mother, son, brother and sister. From the point of view of ethics and scientific principles, inbreeding is absolutely harmful to the evolution of the race, but from the point of view of dog breeding, inbreeding can reduce genetic variation and preserve its original good quality. However, inbreeding may produce particularly good puppies, as well as dogs that are physically inferior, deformed, stunned and sterile. From medicine and eugenics
