==== ''In vitro'' homologous recombination ====
Homologous recombination can be categorized as either ''in vivo'' or ''in vitro. In vitro'' homologous recombination mimics natural ''in vivo'' recombination. These ''in vitro'' recombination methods require high sequence homology between parental sequences. These techniques exploit the natural diversity in parental genes by recombining them to yield chimeric genes. The resulting chimera show a blend of parental characteristics.<ref name=PoluriBook/>{{page needed|date=May 2017}}
