Popis:	The certitude of death makes reproduction the foundation upon which all life-history strategies are based. Plasticity in the reproductive biology of organisms is an essential adaptive response to the capricious and hazardous environments of earth. In this article, we use data from a breeding colony for laboratory mice to examine the mortality risks of offspring born at the outer boundaries of their Dam's reproductive plasticity. Our results suggest that the mortality/survival charac- teristics of offspring are affected by both litter parity and offspring gender. Females born to young Dams have consis- tently longer life spans than females born to older Dams. Conversely, males are either not affected by parental age or have longer life spans when born to older Dams.
