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 generation and maintenance of gametes in a multicellular organism. A gamete is a haploid reproductive cell. The process whereby a relatively unspecialized immature germ cell acquires the specialized features of a mature female gamete. Construction of a stage-1 egg chamber in the anterior part of the germarium, from the progeny of germ-line and somatic stem cells. An example of this is found in Drosophila melanogaster. The self-renewing division of a germline stem cell in the female gonad, to produce a daughter stem cell and a daughter germ cell, which will divide to form the female gametes. Generation of the female gamete; specialised haploid cells produced by meiosis and along with a male gamete takes part in sexual reproduction. Growth of the egg chamber between the time it leaves the germarium and the onset of vitellogenesis. During this time both nurse cells and the oocyte undergo developmental changes including nuclear organization and cytoplasmic growth. An example of this is found in Drosophila melanogaster. Formation of a cluster of germ-line cells, in the female gonad, derived from a single founder cell. An example of this process is found in Drosophila melanogaster. Construction of the vitelline membrane portion of the egg shell, a rigid structure required to maintain the shape of the egg. The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. An example of this is found in Drosophila melanogaster. A reproductive process that is a step in the formation and maturation of an ovum or female gamete from a primordial female germ cell. Construction of the eggshell, a product of the somatic follicle cell epithelium and a structure that supports the egg in a hostile environment, minimizing water loss whilst allowing gas exchanges essential for embryonic respiration. The chromosome organization process by which meiotic chromosomes in the oocyte nucleus cluster together to form a compact spherical structure called the karyosome. The process by which nurse cells undergo apoptosis. During late oogenesis, following the transfer of substances from the nurse cells to the oocyte, nurse cell remnants are cleared from the egg chamber by apoptosis. Transfer of constituents synthesized in the ovarian nurse cells to the oocyte, through the ring canals, as the egg chamber is growing. An example of this is found in Drosophila melanogaster.
