I hate GMO -but what you are talking about is not the kind of GMO people like me hate.

GMO is used to put DNA from pigs, insects etc plus insecticides/herbicides into the DNA of the plants (as they have done with corn; potatoes' tomatoes; wheat; soya beans and many others.

You are talking about taking a gene from a wild banana and placing it in the DNA of the banana...which is similar to the way we evolved our fruits and vegetables and other crops (plus animals, dogs, cats etc) - by selective breeding. That is not dangerous for us, as GMO is.
