Bithorax mutant
WebThe iab-2, 3, and 4 mutant classes define positive cis-regulatory elements that induce expression of abdA in segments A2-A4 (parasegments 7-9), respectively. Once a pattern of abdA expression is turned on in a given parasegment, it remains on in the more posterior parasegments, so that the complex pattern of expression is built up in the ...

WebMar 14, 2013 · In Drosophila melanogaster, the metathoracic haltere is a serial homolog of the mesothoracic wing, as illustrated by the bithorax mutant, which bears metathoracic wings instead of halteres ( 9 ). In Ubx mutant clones, haltere tissue was transformed into wing tissue ( 10 ). WebBithorax mutants transform the anterior compartments of the metathoracic disks (haltere and third leg) into those of the mesothorax (wing and second leg); however, a wild-type …
