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 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. 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. Any process by which a cell is transported to, and/or maintained in, a specific location. 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. Any process by which a cell, a substance, or a cellular entity, such as a protein complex or organelle, is transported to, and/or maintained in a specific location.
