Question

What are gene banks?

Answer 1

1. A type of biorepository that preserves genetic material is called a gene bank.
2. In plants, it could be by freezing the cuttings from the plant or stocking the seeds.
3. For animals, this is the freezing of sperm and eggs in zoological freezers until further need. 
4. Plant genetic material in a 'gene bank' is preserved at −196° Celsius in liquid nitrogen as mature dry seed.
5. In an effort to conserve agricultural biodiversity, gene banks are used to store and conserve the plant genetic resources of major crop plants and their wild relatives.
