With apples you are correct. We will get what we get. No problem for me. As long as we can eat them! It is possible to clone the trees but I really don't have time for this technique.

With other things like nectarines & peaches I believe we should get an exact replica. As for avocados we have a tree here and the flavour is out of this world. Getting them to sprout however I am not having much luck with... yet.
