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. 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. Generation of the female gamete; specialised haploid cells produced by meiosis and along with a male gamete takes part in sexual reproduction. Formation of a single follicular epithelium around the germ-line derived cells of a cyst formed in the germarium. An example of this process is found in Drosophila melanogaster. The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form. A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The process whereby one relatively unspecialized immature cystocyte of the germ-line cyst in the germarium acquires the specialized features of an oocyte. An example of this process can be found in Drosophila melanogaster. Directed movement of the oocyte, following its specification, from its original central position in the cyst to a posterior position relative to the nurse cells of the egg chamber, and its maintenance in this posterior location. This is the first sign of anterior-posterior asymmetry in the developing egg chamber. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the fusome of ovarian cells, an organelle derived from the spectrosome. It anchors the mitotic spindle pole to provide orientation during cystoblast cell divisions. Formation of a cluster of germ-line cells, in the germarium, derived from a single founder cell (cystoblast). An example of this process is found in Drosophila melanogaster. Assembly of the intercellular bridges that connect the germ-line cells of a female cyst.
