But the reasons we are eating these two bananas is that their skin colors align with the ripeness of the fruit in a way that the human brain thinks makes sense. And because we are monocropping, the same family of fungi are now successfully attacking the Cavendish that took out the Gros Michel.

All the other species of bananas tend to turn brown almost immediately after or around the time they are fully ripe, and that makes them less commercially viable.

So I would say that these gene splices are less interesting for the Cavendish directly and more interesting for bringing genetic diversity into the produce isle. We could have five kinds of banana like we have five kinds of pears. Which indirectly helps the Cavendish by slowing down the doom clock on banana plantations.
