Previous localization of breakpoint refined to approximately 9.5--10.75kb upstream of h.
Deletion of upstream regulatory sequences of h, leaving approximately 11kb of upstream sequences intact.
Rearrangement of chromosome upstream of the h promoter. Approximately 10kb of upstream sequences remain intact.
Second thoracic and third abdominal segment is absent in the embryo. T2/A1 and A1/A3 fusions also occur.
Cuticle defects between T1 and A2.
Regulatory mutation causing alterations in hairy expression in cellular blastoderm that result in a partial version of the wild-type pattern (Howard, Ingham and Rushlow, 1988).
Ingham.
Selected on the basis of its failure to complement the bristle phenotype of either h1 or h2. The h49 mutation has a maternal effect on h49 mutant zygotes.
