Meiosis: Is Spermatogenesis Stress an Opportunity for Evolutionary Innovation?

Meiosis: Is Spermatogenesis Stress an Opportunity for Evolutionary Innovation?

Abstract
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.
