Comments on Cytology

Breaks in X estimated from Fig 1 of FBrf0002766. Break in chromosome 2 estimated from position of y+ 1-2 cM to the right of dp.

Left limit of break 1 from polytene analysis (FBrf0039441) Right limit of break 1 from inclusion of arth (FBrf0050547) Left limit of break 2 from polytene analysis (FBrf0039441) Right limit of break 2 from non-inclusion of Cyp4g1 (FBrf0047940) Limits of break 3 from polytene analysis (citation unavailable)

    slight suppression of scutellar chaetae (Garcia-Bellido and Santamaria, 1978). Homozygous clones in wing survive but fail to differentiate sensilla (Schubiger and Palka, 1985, Dev. Biol. 108: 399-410). Df(1)sc19 is deficient for y, ac, sc, and scl but not l(1)1Ac, om, or RpL36; it is male lethal but survives in the heterozygous female. Dp(1;2)sc19 carries, in addition to sc19, normal alleles of y, ac, and scl; it is viable homozygous and does not affect crossing over in 2L. X-ray-induced losses of y+ from the transposed fragment are M and male and female sterile (Velissariou and Ashburner, 1980, Chromosoma 77: 13-27).
