The first two columns of each section include mean raw lengths of midline vault linear distances (mm), followed by SDs in parentheses, for control (+/+) and homozygote null mutant (−/−) specimens of the three most severely affected background/genotype combinations. The third column in each section includes ratios of +/+ length over −/− length.

Ratio value is significantly different from 1.0 (P = 0.05) based on an EDMA (Euclidian Distance Matrix Analysis) FORM difference permutation test.
