Individual Genetic Contributions to Genital Shape Variation between Drosophila simulans and D. mauritiana
Figure 3
Shape measurements in introgression lines. The distribution of the first two principal components obtained from an elliptical Fourier analysis for pure-species D. mauritiana (green triangles) and D. simulans (orange squares) compared to introgression lines (blue diamonds) containing (a) introgressed regions of D. mauritiana in an otherwise D. simulans genetic background (SM) or (b) introgressed regions of D. simulans in an otherwise D. mauritiana genetic background (MS). Ellipses represent the standard deviation centered on the mean value for each group. A representative lobe shape for each line is shown in the same color as the group it represents.
