General Information
Term germarium-derived cystoblast division ID (Ontology) GO:0048142 (Gene Ontology)
Definition The four rounds of incomplete mitosis undergone by a cystoblast to form a 16-cell cyst of interconnected cells within a germarium. 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.[ PubMed:11131529 ]
Also Known As"germarium-derived cystoblast cell division"
