X*Y females exhibit steeper reproductive senescence in the African pygmy mouse.

Proceedings of the National Academy of Sciences of the United States of America - 7 Jan 2025

Abstract excerpt

A wave of studies has recently emphasized the influence of sex chromosomes on both lifespan and actuarial senescence patterns across vertebrates and invertebrates. Basically, the heterogametic sex (XY males in XX/XY systems or ZW females in ZW/ZZ systems) typically displays a lower lifespan and a steeper rate of actuarial senescence than the homogametic sex. However, whether these effects extend to the senescence...
