Figure 7(A-E cntd.)
7D. Relative warps (3X) of a thin plate spline
regression comparison of average landmarks of 12 male and 10 female wings
of Drosophila immigrans.
Similar to D. melanogaster, the major difference between
the male (blue) and female (red) landmarks of D. immigrans
wings is seen to be a dilation of the distal two-thirds of the wing blade
in the male compared to the female.
7E. Relative warps (3X) of a thin plate spline
regression comparison of average landmarks of 27 male and 27 female wings
of wild type Drosophila virilis.
Unlike D. melanogaster and D. immigrans
the major difference between the male and female D. virilis
wings is seen to be a small flextion of the proximal-distal axis of the
wing blade in the male compared to the female. This type of difference
was noted as a minor component in a principal components analysis
of D. melanogaster sex dimorphism.
