Some of the in1 mutant pupal wing cells fail to adopt a hexagonal shape.
Mutants show no significant disruption of ovarian morphology.
Hairs point slightly posteriorly in the C region of the wing. The hairs on the scutellum point anteriorly, and thorax microchaetae are routinely split. In the adult thorax some bristles are split. On the leg, hair polarity is abnormal, and more multiple leg hairs are found than in fz1 mutants. Mispositioned bracts are not a feature of the phenotype, though bracts may be multiplied. Joint duplications are rare.
Viable as a homozygote or a hemizygote. Strong thoracic bristle and wing hair phenotype. Percentage of dorsal wing surface cells that display abnormal cell polarity and the percentage of wing cells forming more than one hair is more severe at 18oC than 29oC.
Many wing cells of homozygous flies form two or three hairs. Homozygous flies have disruptions in the pattern of wing hair polarity. The prehair initiation site is along the cell periphery, but not restricted to the distal vertex in pupal wing cells. Double mutants of in1 with fzunspecified, dsh1 or pk1 resemble in1 single mutants. Double mutants of in1 with mwh1 resemble mwh1 single mutants.
Hairs and bristles on thorax and abdominal tergites, directed irregularly toward midline; trichomes and chaetae on mesonotum coordinately misdirected (Toney and Thompson, 1980). Marginal hairs of wing stand out from wing margin; trichomes on wing blade no longer directed in parallel with longitudinal veins; frequently divergent therefrom. 50-60% of trichome-bearing cells express duplicated or rarely triplicated trichomes. Wings slightly spread and tend to be long and narrow. Somatic clones of homozygous cells in wing described by Gubb and Garcia-Bellido. Incomplete extra leg joints tend to form as mirror-image duplications proximal to the normal joints on tarsal segments three and four (Held, Duarte and Derakhshanian, 1986). RK1.
