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. 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. 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. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. 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. Process by which a germarium-derived cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed. An example of this is found in Drosophila melanogaster. The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
