WebIn meiotic cells there are ‘hot spots’ of recombination – these are places on chromosomes where Spo11 prefers to act. In mitotic cells, recombination occurs most frequently between sister chromatids, which act as a template for DNA repair. By contrast, crossing over in meiotic cells is targeted between homologs.
