Dimorphisms in fru+ Neuronal Arbors

Volume renderings of representative clones with sexually dimorphic projections. Nondimorphic regions are black, male-specific arbors are green, and female-specific arbors are magenta. Note that some black regions look different between the sexes in these examples, but comparison of multiple examples shows that consistent differences are restricted to green and magenta regions. Clones in the left column have dimorphic arbors in both sexes, and representative examples are shown of each of the male and female brains, whereas clones in the right two columns have only male-specific arbors. In all cases, sex-specific arbors are either missing or much weaker in the other sex. Scale bar represents 50 μm. See also Figure S2 and Movie S1.
