Heritability of Directional Asymmetry in Drosophila melanogaster
Figure 2
Mean directional asymmetry (DA) of each generation for four lines, two originally from Florida (FL) and two from Illinois (IL). The -axis shows the mean DA (left-right) value in millimeters for the 100 individuals measured in each line in each generation. indicates means for lines selected to move the crossvein left (to decrease DA value) and those selected to move the crossvein right (to increase DA value).
