The genetics of gender and life span
نویسندگان
چکیده
Several possible and potentially overlapping genetic mechanisms have been suggested to explain differences in life span between males and females. Two recent papers in BMC Evolutionary Biology on the effects of inbreeding provide additional insight into the genetic architecture underlying life span differences between genders in two different insects.

The genetic architecture of life span and mortality rates: gender and species differences in inbreeding load of two seed-feeding beetles.
We examine the inbreeding load for adult life span and mortality rates of two seed beetle species, Callosobruchus maculatus and Stator limbatus. Inbreeding load differs substantially between males and females in both study populations of C. maculatus--life span of inbred females was 9-13% shorter than the life span of outbred females, whereas the life span of inbred males did not differ from th...
