Homeotic selector gene
Encyclopedia
Homeotic selector genes confer segment
identity in Drosophila
. They encode homeodomain proteins which interact with Hox and other homeotic gene
s to initiate segment-specific gene regulation.
An example of a homeotic selector gene is 'Deformed' (Dfd) which signals identity of a mandible.
Segmentation (biology)
Segmentation in biology refers to either a type of gastrointestinal motility or the division of some animal and plant body plans into a series of repetitive segments. This article will focus on the segmentation of animal body plans, specifically using the examples of the phyla Arthropoda,...
identity in Drosophila
Drosophila
Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called "fruit flies" or more appropriately pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit...
