WebMay 13, 1994 · Abstract. In Drosophila, the misexpression or altered activity of genes from the bithorax complex results in homeotic transformations. One of these genes, abd-A, normally specifies the identity of the second through fourth abdominal segments (A2 to A4). In the dominant Hyperabdominal mutations ( Hab ), portions of the third thoracic segment …
WebThe bithorax gene complex in Drosophila contains a minimum of eight genes that seem to code for substances controlling levels of thoracic and abdominal development. The state of repression of at least four of these genes is controlled by cis-regulatory elements and a separate locus (Polycomb) seems to code for a repressor of the complex.The wild-type … orchard supply hardware torranceWebBithorax normally activates a gene that negatively regulates appendages in the abdomen.
