Detailed Description
Statement
Reference

97% of embryos derived from homozygous females are dorsalised.

100% of embryos derived from homozygous or gd9/Df(1)KA10 females have a class I phenotype (they are strongly dorsalised, lacking both ventral denticles and filzkorper).

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.

70% of embryos derived from gd6/gd9 females have a class II phenotype; embryos lack ventral cuticle, the filzkorper are present and increased amounts of cuticle show dorsal characteristics compared to wild-type, embryos are more twisted than class III embryos and are often tube-like, the ventral furrow is absent, there is no sign of mesoderm development and midgut and hindgut is poorly organised. 30% have a class I phenotype; embryos lack ventral cuticle and filzkorper, producing only dorsal cuticle. Embryos derived from gd9/Df(1)KA10 females have a class I phenotype.

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