Question by Plissken: What types of crops are threatened in biodiversity?
I’m reading “Banana: Fate of the Fruit that Changed the World.” The Cavendish banana that most of America eats is in danger of being susceptible to Panama disease which could wipe out whole plantations and spread to others quickly.

What other types of crops are like the Cavendish banana in the sense that the crop is produced in large quantities but is genetically identical?

The only other one I know of is Roudup Ready Corn…what are some others? I ask, because I am thinking of doing a project that outlines some crops that are produced in large quantities but are all genetically identical that serves a large population (i.e. United States) but I would like to cover more than just Bananas and Corn.

Thanks.
