During a brief increase in temperature, cells undergoing spermatogenesis, but not oogenesis, activate transposons. This sexual dimorphism suggests that temperature stress during spermatogenesis provides a unique opportunity for transposons to mobilize and modify genomes, driving evolutionary change without substantially affecting reproduction.

减数分裂:精子发生压力是进化创新的机会吗?
在温度短暂升高期间,经历精子发生而非卵子发生的细胞激活转座子。这种性别二态性表明,精子发生过程中的温度压力为转座子提供了一个独特的机会来动员和修改基因组,从而推动进化变化而不会显着影响繁殖。
