Figure 8.  Similar sex dimorphism measured in multiple wild type strains of  Drosophila melanogaster using thin plate spline methodology.  Combined Relative Warp analysis of the 6 average wings (male and female of each of the three wild-type strains) allows separation of three principle components of Relative Warp (A, B and C, containing 98% of the explainable variability of the five available principle components) which have similar (parallel) sex dimorphism components.
