Distribution of variance components across the face. (A–C) The anatomical distribution of phenotypic and genetic variances as well as heritabilities is shown. These are represented as heatmaps based on a thin-plate-spine morph as described in Materials and Methods. (D) The heritability estimates or the Procrustes-superimposed symmetrized landmarks are shown. (E) The vectors, magnified 10-fold, used to generate the heritability heatmap are depicted.
