The abdominal segments of Drosophila have no appendages. Loss of function of bithorax genes results in appendages forming in these abdominal segments.  Therefore, ________.

▸ bithorax mutations are necessarily recessive

▸ bithorax genes normally activate appendage-forming genes

▸ ultrabithorax usually acts to oppose bithorax genes

▸ bithorax normally activates a gene that negatively regulates appendages in the abdomen

▸ expression of bithorax wild-type genes suppresses all appendage formation
