| 内容記述 | Since the orientation of unfertilized eggs and the righting of eggs after grey crescent formation do not affect the axes, attention here is directed toward a comparative study of the initial rotation of the fertilized egg, the so-called rotation of orientation (R-of-O). The goal of the investigation is to determine the timing and dynamics of the R-of-O (as distinct from inversion rotations), to confirm prior observations, and to examine the influence of gravity compensation at periods that might be crucial. Gravity compensation for 1 hr during the R-of-O is found to yield fewer abnormalities. It is hypothesized that it changes the axes and that return to normal conditions permits regulation. Longer exposure is found to yield more abnormalities, perhaps by perturbing both the action of the aster and regulation. |
