Software Gene Recombination

Evolution of software is an important issue to users and developers. Gene recombination is an evolutional technology in biological gene engineering. For the software evolutional issue, this paper proposes a Gene Recombination Model, encompassing the six sub-models, homologous recombination, site-specific recombination, double strand break recombination, chromosome rearrangement, template-selective recombination and transposition recombination. The usage, step and limitation of the model are presented at last.
