Figure 3

Hybrid genital shape. Bivariate plot of mean shape scores of each genotype for the first two principal dimensions of shape variation (and percent of variance explained). The lines drawn connect genotypes involved in the same cross. Outlines below the graphic depict the genital shape variation accounted for the first principal component. Outlines to the left of the plot represent the genital shape variation accounted for the second principal component. Dk: Drosophila koepferae; Db: Drosophila buzzatii, F1: hybrids. Cross 3512 (); Cross 4853 (■); Cross 4855 (); Cross 8832 (▲).
