Individual Genetic Contributions to Genital Shape Variation between Drosophila simulans and D. mauritiana
Figure 1
The male posterior lobe in D. simulans (a) and D. mauritiana (b). A horizontal line was drawn at the base of the arch of D. simulans (c) and D. mauritiana (d); the area enclosed within the resulting outline was measured as the area; the length from the line to the furthest point was the length; the widest point that was at least 25 μm from the base was the width. Scale bars are 25 μm.
