Cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as:
- In situ conservation by sacred groves
- In situ conservation of biodiversity
- In situ cryo-conservation of biodiversity
- Advanced ex-situ conservation of biodiversity
Answer
(4) Advanced ex-situ conservation of biodiversity
Solution
As per NCERT, in recent years ex situ conservation has advanced beyond keeping threatened species.
⇒ Gametes of threatened species can now be preserved in viable and fertile condition for long periods using cryopreservation techniques.
∵ The gametes are kept away from the natural habitat (off site) ⇒ it is ex situ conservation.
∴ It is advanced ex-situ conservation of biodiversity.
