Genetically, all bananas are genetically similar...to grow trees you plant shoots, because they don't have seeds.
They are worried about pests destroying all bananas. Finding strains with resistance is a big deal.
And they are working on GM plants too.
Humans share 50% DNA with bananas
Eat a banana of the variety typically sold in American markets, then a plantain, then one of the short, fat, thin-skinned deliciously sweet kinds seldom sold here. Then tell me they are all the same.
Kinda like saying that iguana, rattlesnake and capybaras "all taste like chicken".
