Genetic variation of morphological traits in Drosophila melanogaster under poor nutrition: isofemale lines and offspring--parent regression.

Abstract excerpt

Variation of three morphological traits (thorax length, wing length and sternopleural bristle number) was examined in Drosophila melanogaster reared on a medium with low yeast content and on a standard medium using the isofemale line analysis and offspring--parent regression. The aim was to test whether these experimental approaches give different patterns of changes in genetic variability estimates when...
