OXIDATIVE STRESS HYPOTHESIS. “This scenario presupposes that DNA maintenance is inefficient in the absence of meiosis; however, prokaryotes (including archaea) have efficient repair mechanisms that involve recombination but not meiosis. In addition, this scenario does not fit well with the observation that a large number of DSBs are actively generated at the onset of meiosis.” (DSB = double strand breaks).
