This page introduces the fly, drosophila, as a developmental model organism. The small drosophila fruitfly has been used by genetisists for many years now and much is now understood about its development in relation to gene expression and regulatory mechanisms.
In recent years, using developmental mutants, many mechanisms of development in the fly have been shown to be almost identical to those seen in humans and other animals. In fact, these developmental mechanisms have become the "paradigm" for our understanding of development.
The fruitfly (drosophila) was and is the traditional geneticist's tool. It has been transformed to an magnificent tool for the embryologist, with many developmental mechanisms being uncovered in this system combined with homolgy gene searches in other species.
There is also a difference in basic body structure between males and females, males lack the seventh abdominal segment (A7) present in females. This has recently been shown to be due to a down-regulation of epidermal growth factor receptor (EGFR) activity and fewer histoblasts in the male A7 in the early pupae.

The drosophila lifespan varies with temperature and is about 30 days at 29 °C.

This is the classic mutation that gave rise to the discovery of Hox genes and other genes related to body pattern formation. In this mutant during development the fly embryo incorrectly positioned where (antenna) should have be two legs (pedia). The discovery of this mutant in Walter Gehring's lab opened up the field of developmental genes and this field has been rewarded with the 1995 Nobel prize in Medicine.
The Hippo (Hpo) pathway, first identified in Drosophila, controls organ size by regulating cell proliferation (inhibition) and apoptosis (induction). In contrast, the TOR signalling pathway regulates organ size by stimulating cell growth, thus increasing cell size.
