l(3)87Df2/l(3)87Df3 survivors show thin, short bristles. l(3)87Df2/l(3)87Df3 show no survival at 18oC, rare survivors at 25oC and full survival at 29oC. l(3)87Df3 is homozygous viable at 27-29oC, though eclosion is delayed with respect to wild type controls. Shifting l(3)87Df3 to non-permissive temperatures within a few hours of eclosion results in complete sterility of females. Temperature shift experiments indicate that l(3)87Df function is required throughout development.
Low hemizygous viability. Survivors have very thin and short thoracic bristles.
Surviving cold-sensitive mutants display a phenotypic syndrome that can include delayed development, abnormal bristle morphology and female sterility.
l(3)87Df3 is rescued by l(3)87Df+t8.1
Lethality is rescued by l(3)87Df+t8.1. l(3)87Df2/l(3)87Df3 produces rare adult survivors.
Does not fully complement l(3)87Df2.
