| In the case of developing eggs, the diploid oogonia continue to divide mitotically for a short time in the ovary. |
| In the rotting tissues branches of the older mycelium similarly swell up and form antheridia and oogonia. |
| Meiosis occurs just before mating in well-differentiated oogonia and antheridia. |
| The germinal epithelium is composed of epithelial cells that become prefollicle cells when associated with oogonia, as in Fundulus grandis. |
| During human fetal development, the primordial germ cells migrate to and are incorporated within the developing ovary and are termed oogonia. |
| The oogonia multiply by mitosis, but early in fetal life, they enter meiosis. |
