Özet

Offspring from Drosophila melanogaster populations of different maternal age were derived and aged. Our results showed that offspring longevities do not follow inversely the mother's ages i.e., increasing age of the mothers do not result in decreased offspring mean longevities in general (no typical Lansing effect). We found that also each population has distinct offspring age specific mortality rates with increasing maternal age. Overall, we suggest, this may point to unique genetic background effect of each particular population has on longevities within context of maternal age, considering that populations studied would signify distinct genetic variation states of samples of different geographic origin.
