Zoo starts sperm bank for wildlife Singapore - Genetic material including sperm and tissue samples collected by the Singapore Zoological Gardens will be used to clone wildlife, the Straits Times reported on Monday. WRS manages the zoo. Cloning would help prevent endangered species from becoming extinct, officials from the zoo said.
Cloning has a place in conservation.
The zoo has so far collected tissue and sperm samples from seven animal species, which are stored frozen at minus 170 degrees Celsius in liquid nitrogen tanks.
