Timed cell lineage of M. membranacea and the break of biradial symmetry. Panels on the bottom show the developmental stages with the cell tracing overlay until 48 cells. The outlines in the last two panels (>61 and > 79 cells) indicate the cells 1ae 11–1de 11, and the prominent delay in the division of 1de 11. The anteroposterior axis is denoted by a dashed line in the last panel. Quadrant color coding: A (green), B (blue), C (purple), D (red)
