Figure 6

Positive (red) and negative (blue) rotational strain quantified by curl at 8 (80% epiboly), 9 (90% epiboly), 10 (bud, 100% epiboly), and 10.5 hpf (1-somite). In (A), (B), and (C), the embryo is oriented with anterior and posterior to the top and bottom. Positive curl is clockwise, negative curl is counter-clockwise. (A) Curl map of rotational strain over the dorsal view of the embryo. (B) Right side view of rotational strain of the embryo. (Dorsal is in the left side). (C) Curl map of rotational strain over the ventral view of the embryo. (D) Left side view of rotational strain of the embryo (dorsal is in the right side).
