CharlieDigital said:This reminds me of some stuff I read (or watching on TV...can't remember) a while ago regarding navel oranges and avocados: they are essentially all copies of a single genetic anomaly since they are all propagated through graftings either directly from the original plant or some descendants of the original plant (moreso with Navel oranges)
Interestingly, the Cavendish banana may eventually die out due to this reason − the lack of genetic diversity gives it no defense against Panama disease, which will cause the Cavendish to be nearly wiped out.
The Cavendish itself was a replacement for the Gros Michel ("Big Mike") banana, which was the main banana in markets prior to 1950s − research is going on to either replace the Cavendish with a new variety of Banana or use genetic modification to allow bananas to resist diseases.
Also, here's another picture of a wild Banana:
Those things are hard seeds − sounds really nasty.
