Principal Component Analysis (PCA) of preanal appendage shape, male genitalia. Showing the four major principal components (PCs) (90.59% of the total variance). The percentage of shape variance represented by each PC is presented along the axes. Thin-plate splines show the degree of shape deformation from the mean overall shape.
