Breakpoint mapped to within a 1.7kb EcoRI fragment spanning from approximately 2 to 4kb 3' to the transcription unit.
break at about 105 kb; 3' to putative coding region. Coordinates estimated from Cohen, Broenner, Kuettner, Jurgens and Jaeckle (1989); origin undefined; positive values extend to left.
Stage 12 homozygous embryos show normal or near normal pattern of transcripts in the ventral maxillary domain.
Heterozygotes show a transformation of antenna to leg. Homozygous and hemizygous embryos lack the H piece, labial sense organ, antennal sense organ, maxillary sense organ and Keilin's organs.
