Extended Data Fig. 1: Hierarchical spectral clustering of facial shape.
From: Insights into the genetic architecture of the human face
a, Global-to-local facial segmentation of all 3D images (nTotal = 8,246), obtained using hierarchical spectral clustering. Segments are colored in teal and identical to those in Fig. 1. Roman numerals represent ‘quadrants’ of facial segments. b, The number of principal components retained after parallel analysis for each facial segment.
