The first of these steps, strand exchange, involves pairing of the broken dna end with the homologous region of its sister chromatid, followed by strand invasion to form a dna crossover or holliday junction. Most molecular models for homologous recombination describe the process in terms of three key steps. In asexual organisms, the study of mitotic recombination is one way to understand genetic linkage because it is the only source of recombination within an individual.

Mitotic recombination is a type of genetic recombination that may occur in somatic cells during their preparation for mitosis in both sexual and asexual organisms. This occurs during the creation of an egg or sperm for the next generation. The identification of a protein complex that catalyses branch migration and holliday junction resolution argues that the mechanism of homologous recombination is conserved from bacteria to man.
