Phenotypic plasticity of body pigmentation in Drosophila melanogaster: genetic repeatability of quantitative parameters in two successive generations.

Abstract excerpt

In Drosophila melanogaster, body pigmentation is a quantitative trait that depends on developmental temperature. When investigated over the whole thermal range of the species, pigmentation exhibits nonlinear reaction norms that differ among segments. The isofemale line method was used to analyse the genetic variability in two natural populations that affected the shape of reaction norms. Each line was considered...
