Half-sib analysis of three morphological traits in Drosophila melanogaster under poor nutrition.

Abstract excerpt

Variation in thorax length, wing length and sternopleural bristle number was examined in Drosophila melanogaster reared in stressful and nonstressful environments using paternal half-sib design. Low concentration of yeast in the medium was used as a stress factor. Phenotypic variation of thorax length and wing length was higher under poor nutrition than in the control; in bristle number, phenotypic variation was...
