To study pathways that lead to aneuploidy during aging, the authors provide a system that enables cohesion protein depletion in mouse oocytes, mimicking effects that occur during aging. They uncover a threshold for cohesion loss driving chromosome errors and show that actin and centromere defects amplify aneuploidy.
