Geographic differentiation in wing shape inDrosophila melanogaster
Genetic variation of a suite of 12 morphometric wing characters was examined in 16 natural populations ofDrosophila melanogaster from Eastern Europe and Central Asia using principal component analysis. The posterior wing compartment was found to differ in shape between the Eastern European and Central Asian populations. This result is in agreement with data on wing shape variation from exposure to high and low temperatures under laboratory conditions.
