... of the mouthparts selector proboscipedia ( pb ) directs a homeotic antenna-to-maxillary palp transformation. It also induces a dosage-sensitive eye loss that we used to screen for dominant Enhancer mutations. Four such Enhancer mutations were alleles of the eyeless ( ey ) gene that encode truncated EY proteins...
