Well if bananas weren't genetically similar to us you couldn't eat them, could you. (Well, they taste disgusting anyway, its a wonder anyone can.) If they were genetically totally different you'd take a bite out of one and find yourself with a mouthful of organonitrates, thiols, organophosphates, nitriles, iodides, and lots of other nasty stuff that is really best left out of fruit salads. Actually I would probably prefer the taste of a broad spectrum cholinestrase inhibitor to a banana.
