Phenotypic plasticity of sternopleural bristle number in temperate and tropical populations of Drosophila melanogaster.

Genetical research - 1 Feb 2003

Moreteau Brigitte, Gibert Patricia, Delpuech Jean-Marie, Petavy Georges, David Jean R

Abstract excerpt

We investigated the phenotypic plasticity of sternopleural bristle (SB) number as a function of growth temperature in isofemale lines from temperate (France) and tropical (Congo) populations of Drosophila melanogaster. We found concave reaction norms with a maximum in the middle of the thermal range, except in four African lines which exhibited a regularly decreasing response curve. Genetic variability...
