EOG8SR09W GO:0005634 27/143 nucleus cellular_component "A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent."

Upon specification, the cell fate can be reversed." [GOC:mtg_sensu] EOG8SR09W GO:0016319 1/143 mushroom body development biological_process "The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells."

[GOC:go_curators] EOG8SR09W GO:0007483 1/143 genital disc morphogenesis biological_process "The process in which the anatomical structures derived from the genital disc are generated and organized. This includes the transformation of a genital imaginal disc from a monolayered epithelium in the larvae of holometabolous insects into the recognizable adult genital structures, the anal plates and the hind gut."

[GOC:bf] EOG8SR09W GO:0035263 1/143 genital disc sexually dimorphic development biological_process "The sex-specific patterns of primoridia growth and differentiation in the genital imaginal disc. The anal primordium of the genital disc develops in both sexes, but depending on the genetic sex gives rise to either male or female analia. Depending on the genetic sex, only one of the two genital primordia develop. In females the female genital primordium develops and gives rise to the female genitalia whereas the male primordium is repressed. Conversely, in males the male genital primordium develops and gives rise to the male genitalia whereas the female genital primordium is repressed." [PMID:11290302, PMID:11494318, PMID:11702781] EOG8SR09W GO:0010629 1/143 negative regulation of gene expression biological_process "Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form." [GOC:dph, GOC:tb] EOG8SR09W GO:0048749 1/143 compound eye development biological_process "The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye."

[GOC:bf] EOG8SR09W GO:0035215 1/143 genital disc development biological_process "Progression of the genital imaginal disc over time, from its initial formation through to its metamorphosis to form the adult terminalia, comprising the entire set of internal and external genitalia and analia. Both sexes of Drosophila have a single genital disc formed from the female and male genital primordia, and the anal primordium. The anal primordium develops in both sexes, forming either male or female analia. However, only one of the genital primordia develops in each sex, forming either the male or the female genitalia."

Paired spermathecae lie at the anterior end of the insect uterus on the dorsal side. Each spermatheca consists of an oval shaped capsule, connected to the uterus by a spermathecal stalk."
