Detailed explanation-1: -The captive breeding of endangered wildlife animals is often necessary for their conservation. It prevents the extinction of a species, subspecies or population. Small captive populations are likely to become extinct.
Detailed explanation-2: -Captive breeding prevents extinction, disease, and other threats to animals. Captive breeding improves animal living conditions. Zoos and public aquariums educate visitors about species conservation and protection.
Detailed explanation-3: -Genetic and demographic management of captive populations focuses on maintaining genetic diversity in order to minimize undesirable genetic changes due to selection in the captive environment, avoid deleterious effects of in-breeding depression, and maintain future options for genetic management.
Detailed explanation-4: -Captive-breeding programs breed endangered species in zoos and other facilities to build a healthy population of the animals. Species-survival plans coordinate with zoos around the world to bring species together for breeding that ensures genetic diversity.
Detailed explanation-5: -Answer and Explanation: Breeding programs maintain biodiversity by protecting endangered species from extinction. These programs bring together individual members of a species to ensure their reproduction, adding to their total numbers.
