Plot of oocyte AR ( b ) and the distance from the AP and VP to the CM ( c ) as a function of time after fertilization (0 min, dashed vertical line). The dotted line at 0 min indicates the fertilization time point. The pink-shaded area corresponds to CP initiation, the orange-shaded area to CP expansion, and the grey-shaded area to CP absorption. N = 8 animals, n = 10 oocytes. Error bars, standard error of the mean (s.e.m.).
