A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents. The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster. The stage in mammalian oogenesis when the primordial germ cell is hardly distinguishable from other cortical cells of the ovary. Generation of the female gamete; specialised haploid cells produced by meiosis and along with a male gamete takes part in sexual reproduction. The stage in oogenesis when the oocyte has a nucleus slightly larger than those of the adjacent cells and is surrounded by a layer of loose squamous epithelial cells. The stage in oogenesis when the antral spaces become distinct and the first polar body forms. The process, occurring above the cellular level, that is pertinent to the reproductive function of a multicellular organism. This includes the integrated processes at the level of tissues and organs. The stage in oogenesis when antral spaces begin to form in the follicle cells. Mitochondria form centers for yolk concentration. Any biological process, occurring at the level of a multicellular organism, pertinent to its function. The stage in oogenesis when the antrum is swollen with follicular fluid. The ovum is ready to erupt from the ovary and is arrested at metaphase of the second meiotic division. The stage in oogenesis when the antral spaces fuse to form a single antral space. The oocyte is suspended in the cumulus oophorous and the first polar body in the perivitelline space. A reproductive process that is a step in the formation and maturation of an ovum or female gamete from a primordial female germ cell. The stage in oogenesis when a single layer of cuboidal follicle cells surrounds the oocyte. The oocyte nucleus is large. The stage in oogenesis when many layers of follicle cells surround the oocyte. There is a yolk nucleus (Balbiani's Body) near the germinal vesicle. The stage in oogenesis when a double layer of distinct follicle cells surrounds the oocyte. An example of this process is found in Mus musculus. The biological process by which new individuals are produced by one or two multicellular organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
