During the next decade, experiments in Drosophila, budding yeast and mammalian cells led to the emergence of other models of homologous recombination, called SDSA pathways, which do not always rely on Holliday junctions.
Durante a seguinte década, os experimentos en Drosophila, lévedos e células de mamíferos utilizáronse para presentar outros modelos de recombinación homóloga, chamados vías SDSA, que non sempre dependen das unións de Holliday.
