Viable material of endangered species can be preserved by :
A
Gene bank
B
Gene library
C
Herbarium
D
Gene pool
Detailed Solution
Gene banks store viable genetic material (seeds, pollen, sperm, eggs, embryos, tissues) of plants and animals, often by cryopreservation at –196 °C in liquid nitrogen.
This keeps the material alive (viable) for long periods, so it can be used later for breeding and reintroduction of endangered species.
A herbarium stores dried, dead specimens; a gene library is a collection of cloned DNA fragments; a gene pool is all the genes of a population.
So viable material of endangered species can be preserved in a gene bank.
