Detailed Description
Statement
Reference

4% of embryos derived from homozygous females have a class I phenotype (they are strongly dorsalised, lacking both ventral denticles and filzkorper), 27% have a class II phenotype (they lack ventral denticles but have filzkorper), 69% have a class III phenotype (they have ventral denticles) and 0% have a class H phenotype (they are phenotypically normal and hatch). 11% of embryos derived from gd1/Df(1)KA10 females have a class I phenotype and 89% have a class II phenotype.

Hyperplastic overgrowth mutant. Apico-lateral junctional complexes appear normal.

Transheterozygous combinations of gd mutations produce a range of cuticular phenotypes, ranging from cuticle only having dorsal characteristics, to cuticle having some ventral characteristics, such as ventral setal belts, depending on the alleles used. Some combinations of alleles complement each other. Homozygous gd1 females show temperature sensitivity in the amount of hatching, and the severity of their offspring's dorsalised phenotype.

98% of embryos derived from gd1/gd6 females hatch. 90% of embryos derived from gd1/gd5 females have a class III phenotype; ventral cuticle is reduced, but some ventral abdominal setal belt material is retained, the anterior midgut invagination and ventral furrow are reduced or absent, gut formation is abnormal and the tracheal pits are located closer to the ventral midline than normal.

Comments
Comments

The addition of wild-type gd from the paternal genome does not alter the frequency of hatching in embryos derived from gd1/gd10 transheterozygotes, indicating that the requirement for gd is strictly maternal. Germline clonal analysis shows that gd is required in the germline. Temperature shift experiments show that functional gd is required late in oogenesis and early in embryogenesis.

Approximate order of allelic severity, from weakest to strongest is: gd5 > gd1 > gd3 > gd6 > gd2 > gd4 > gd7 = gd8 = gd9 = gd10 = gd11 = gd12.
