Hello,
I have a rhubarb plant that's descended from my great grandfather’s garden.  He originally had the plant, split it and gave some to my grandfather who in turn did the same to my father, and my father repeated this, resulting in the plant that I now have in the garden.  So my question is: does my 4th generation plant share the identical DNA profile of my great grandfather’s rhubarb or will the plants evolve to create their own unique DNA?
