Inbreeding in animals examples
WebContinued inbreeding results in offspring that are very genetically alike. After many generations of inbreeding, the offspring will be almost genetically identical, and will produce identical offspring. When this happens, an organism is described as inbred or purebred. Examples of purebred animals are Labrador Retriever dogs and Siamese cats.
