(13) The dorsal and ventral histoblast nests within the first abdominal (A1) segment are shown not to be segmentally homologous with the metathoracic (T3) haltere and leg discs, respectively, since they occur at distinct dorso-ventral locations during normal development and can be found together within the same segment in mutants of the Bithorax complex (BX-C) where T3 is transformed towards A2-A4 or A1 towards T3.

(16) We use a mutant (Haltere-mimic) to show that sequences that normally restrict segmental expression of Ubx in the ectoderm are located downstream from the RNA leader.
(17) The postbithorax (pbx) mutant, which transforms the posterior haltere into a structure resembling the posterior wing blade, reveals an aldehyde oxidase staining pattern in the haltere disc characteristic of the posterior side of the wing disc pouch.
(18) It is shown here that the transformed haltere disc closely resembles the previously established pattern in the wing disc with respect to aldehyde oxidase distribution.
(19) While circulating insulin levels may at times appear to be normal or even elevated in patients with NIDDM, depending on the control group for comparison and the glucose level at which subjects are studied, a profound impairment of pancreatic B-cell function is characteristic of NIDDM and contributes to the hyperglycemia in this condition (Halter, et al., 1985).
(20) We also report an exceptional vg allele (vg83b27) that produces an extreme wing and haltere phenotype, but which defines a second vg complementation unit.
