Cleaved DNA fragments from 2 sources can only recombine artificially.  This does not occur naturally.  Recombination is accomplished by chemically altering one strand, resulting in the removal of a sequence of bases, then altering a second DNA strand from another source with the same base sequence as the first strand, so the second strand's bases align with the first.  This creates a new molecule.
