Drosophila Melanogaster İzosoylarında Besin Kısıtlamasının Gelişim Süresi ve Yumurta Veriminin Eklemeli Genetik Varyanslarına Etkilerinin Araştırılması

Abstract

An organism's adaptation in nature depends on lifetime strategies it can produce against changing environmental conditions. Life history traits have important roles in organism s fitness. In our study we investigated four life history traits which should impact on fitness. The chosen traits are developmental time, viability, fecundity and starvation resistance. We used dietary restriction as an environmental stress factor and looked for the effects of dietary restriction on these life history traits. The main aim of our research is to show how narrow-sense heritability, additive genetic variance and evolvabilities of the traits change under stressfull conditions.
