Genetic components in a thermal developmental plasticity of the beetle Tribolium castaneum.

Abstract excerpt

Low developmental temperatures cause ectotherms to retard growth, postpone maturation, and emerge at either larger or smaller adult size. In this study, we explored how these thermal responses evolved, focusing on their genetic basis. We applied a full diallel breeding design on inbred lines of the flour beetle, Tribolium castaneum. To assess the proportional contributions of genetic and non-genetic effects, each...
