Procrustes distances below diagonal, P-values above. Significant distances after Bonferroni adjustment in bold (α = 0.0017). The three fixation groups (1% glutaraldehyde: 4% PFA, 5% glutaraldehyde: 4% PFA, Bouin's solution post-fixation) are designated 1%, 5% and B, respectively. Sequential treatment steps of embryo harvesting, fixation, and post-scanning are designated F, PS, and H, respectively.
