In non-mammals, this process includes the creation of lampbrush chromosomes. Danilchik and Gerhart studied this process in Xenopus, discovering that it results in asymmetrical distribution of vitellin with respect to the animal-vegetal pole. This process is preceded by one in which a cell is surrounded by granulosa cells and multiple fluid filled vesicles form a single antrum; that process is (*) folliculogenesis and involves formation of the zona pellucida. This process may be distinguished from a similar one by the asymmetrical nature of its cytokinesis phases. Because this process has two divisions but only produces one functional cell, the other two or three polar bodies must be disposed of. For 10 points, identify this female process of gametogenesis, which produces egg cells.
