WebThe homeotic genes determine the characteristic development (identity) of Drosophila body segments ( Lawrence and Morata 1994; Lawrence and Struhl 1996 ). They encode proteins that contain a DNA-binding domain known as a homeodomain and regulate the transcription of target genes by binding to their regulatory sequences. WebThe Homeotic Selector Genes Pair rule and gap genes interact to regulate homeotic selector genes, which specific characteristic structures of segments. Most of these genes are contained in two regions of chromosome 3: the antenna-pedia complex (genes specify head and thoracic segments) and the bithorax complex (thoracic and abdominal segments).
