The fundamental principles underlying animal breeding is based on

Animal breeding is a process of selecting certain animals and allowing them to reproduce in order to produce offspring with desirable traits. The fundamental principles underlying animal breeding are based on genetics. In other words, traits that are inherited from the parents can be selected for and amplified in future generations. By carefully selecting animals with desirable traits and allowing them to mate, breeders can create a population of animals with the desired characteristics. This process can be guided by understanding of genetics, such as how certain traits are inherited and how to predict the likelihood of specific traits being expressed in offspring. Management and physiology are also important factors in animal breeding, but they are ultimately based on the genetic principles.
