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. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. 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. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition. Generation of the female gamete; specialised haploid cells produced by meiosis and along with a male gamete takes part in sexual reproduction. The process whose specific outcome is the progression of an oocyte over time, from initial commitment of the cell to its specific fate, to the fully functional differentiated cell. 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. 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 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 process whereby the developmental fate of a cell becomes restricted such that it will develop into an oocyte.
