Df(3R)D1C12w- homozygotes and Df(3R)D1C12w-/Df(3R)Exel6152 females are fertile.
Df(3R)D1C12w-/Df(3R)BSC24 flies are viable and aphenotypic.
Df(3R)D1C12w-/Df(3R)D14A flies are viable and aphenotypic.
Df(3R)D1C12w-/Df(3R)Exel6152 flies are viable and aphenotypic.
Neither dominant enhancement nor suppression of PEV of the w gene in In(1)wm4 by Df(3R)D170-7/Df(3R)D1C12w- or Df(3R)D14A/Df(3R)D1C12w- is observed.
Neither dominant enhancement nor suppression of variegation of the bw gene in bwD or Dp(2;2)Su(Pm) by Df(3R)D1C12w- is observed.
