The four small micromeres of the sea urchin embryo contribute only to the coelomic sacs, which produce major components of the adult body plan during postembryonic development. To test the proposition that the small micromeres are the definitive primordial germ cell lineage of the sea urchin, we deleted their 4th cleavage parents, and raised the deleted embryos through larval life and metamorphosis to sexual maturity. Almost all of the experimental animals produced functional gametes, excluding… CONTINUE READING
