Ilyanassa eggs pinch off two polar bodies at the animal pole prior to the first cell division. During prophase and early metaphase the meiotic apparatus is separated from the cortex by a layer of lipid droplets and can be found in any orientation relative to the cell surface. As the astral microtubules grow, the meiotic apparatus appears to be pushed toward the animal cell surface by the expanding internal aster. By late metaphase and early anaphase the peripheral aster first flattens and then… Expand
