Yes, your seed-derived plant would be genetically different from its parent, just as you are different from yours. Even though your DNA came from your parents, there is lots or recombination that results in variation being introduced into your genetic sequences.
Using artificial techniques, the only methods to get genetically-identical plants would be by taking cutings and getting them to root, by grafting, or by more modern molecular biology techniques involving introducing nuclei from one plant into a receptive cell. These approaches are all being used to create clones of the oldest or biggest trees across the U.S. Recently, seedlings of Methusala (sp?), the oldest known bristlecone pine from the White Mountains (just west of DV) were produced from seeds and will be used to accept grafts from the mother tree, thereby creating genetically-identical descendents of this tree.
