    chloe, I can't answer your question specifically. DNA finger printing shouldn't be affected too much, unless an individual engineers an faux genome, which would likely have extremely ontological complications. But genetic engineering could (and will) have tremendous implications for evolution and speciation. Consider this:

    Craig Venter's lab succeeds in Digital Life Design (DLD). It announces the first synthesis of a bacterial genome and the development of DLD synthetic life:
    ...In June 2007 another major advance was achieved when JCVI researchers led by Carole Lartigue, Ph.D., announced the results of work on genome transplantation methods allowing them to transform one type of bacteria into another type dictated by the transplanted chromosome. The work was published in the journal Science, and outlined the methods and techniques used to change one bacterial species, Mycoplasma capricolum, into another, Mycoplasma mycoides Large Colony (LC), by replacing one organism’s genome with the other one’s genome.

    Genome transplantation was the first essential enabling step in the field of synthetic genomics as it is a key mechanism by which chemically synthesized chromosomes can be activated into viable living cells. Today’s announcement of the successful synthesis of the M. genitalium genome is the second step leading to the next experiments to transplant a fully synthetic bacterial chromosome into a living organism and “boot up” the cell.
    From an interesting EDGE discussion between Richard Dawkins and Craig Venter, under the subtitle, LIFE: A GENE-CENTRIC VIEW:

    DAWKINS: It’s more than just saying you can pick up a chromosome and put it in somewhere else. It is pure information. You could put it into a printed book. You could send it over the Internet. You could store it on a magnetic disk for a thousand years, and then in a thousand years’ time, with the technology that they’ll have then, it would be possible to reconstruct whatever living organism was here now. What has happened is that genetics has become a branch of information technology. It is pure information; it’s digital information; it’s precisely the kind of information that can be translated digit-for-digit, byte-for-byte into any other kind of information.
    VENTER: Biology is the ultimate nanotechnology and it can now be digitally designed and reconstructed.
    Natural selection may never be the same after this. But DNA fingerprinting shouldn't be affected. In either case, it will be a digital affair.

    DNA is the blueprint for the individuality of an organism. The organism trusts upon the information stored in its DNA for the direction of every biochemical process. The life, development and unique features of the organism depend on its DNA. The sections of DNA which have been associated with particular features or functions of an organism are called genes.
