Dorsal and ventral sides of the embryo have different geometric features. (A) Illustration showing different distances in geometry. (B) Digital image from DAPI channel of a wt (w1118) embryo to illustrate the parameters used to analyze geometric features in this study. (C) Relative differences (with error bar shown) in contour distances between the dorsal and ventral sides (Δcembryo/CD) as a function of fractional embryo length (x/L) from 28 wt embryos at early nuclear cycle 14. All distances along the A-P axis in this report are measured from the anterior pole unless otherwise stated.
