The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. 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 four rounds of incomplete mitosis undergone by the cystoblast to form a 16-cell cyst. Within the cyst, one cell differentiates into an oocyte while the rest become nurse cells. 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. 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. The process whose specific outcome is the progression of an immature germ cell over time, from its formation to the mature structure (gamete). A germ cell is any reproductive cell in a multicellular organism. The four rounds of incomplete mitosis undergone by a cystoblast derived from the germarium to form a 16-cell cyst. Within the cyst, one cell differentiates into an oocyte while the rest become nurse cells. An example of this process is found in Drosophila melanogaster.
