Figure 1From: Distance measurements via the morphogen gradient of Bicoid in Drosophila embryosDorsal 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.Back to article page
