Maintains intact sc regulatory regions.
The notum lacks bristles and sensory organ precursor cells are absent in the wing disc in hemizygous males.
Adults do not develop bristles on the notum. Residual bristle formation is seen in the legs.
Hemizygous pharate adult males completely lack interommatidial bristles.
Df(1)sc10-1 adults lack all external sensory organs in the notum.
Mutant adults have no bristles on the notum, but have a normal pattern of correctly attached flight muscles.
Df(1)sc10-1/Y flies have a bald notum.
Df(1)sc10-1/Y flies are almost completely bald, lacking most mechanosensory organs. Most sensory organ precursor cells are missing in the wing discs of these animals.
Flies are almost devoid of micro- and macrochaetae.
Flies hemizygous for Df(1)sc10-1 have bald nota, no SOPs are specified.
Flies lack all sensory bristles. Scer\GAL4455.2-mediated expression of Ggal\Cash4UAS.cHa in the scutellar primordia induces ectopic scutellar bristles.
Olfactory sensilla on the surface of the third antennal segment develop normally in Df(1)sc10-1 flies.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Glial cells of wing nerves are absent in adult wing and almost completely absent in the developing wing.
Homozygotes exhibit few bristles. Heat induced expression of P{CnASH} induces bristle formation on the thorax and distal segments of the legs.
Loss of all bristles on the notum.
Hemizygotes fail to develop most of the adult external mechanosensory organs (FBrf0045760). Flies have low viability associated with severe uncoordination: unable to walk or stay upright.
Viability is low although a few hemizygous males survive to adulthood. two P-type (P3 and P4) and one S-type bristle are present on the proboscis of surviving hemizygotes, all other bristles normally present on the proboscis are absent. Df(1)sc10-1 flies carrying schs.PR can develop the complete labellum bristle pattern, when they are heat shocked at 0, 6 and 12 hours after puparium formation.
male viability low The adults, which occasionally eclose, lack macro- and microchaetae, except those of the eye and wing margin. Homozygous cell clones in wing lack neurons except along anterior margin (Schubiger and Palka, 1985, Dev. Biol. 108: 399-410).
