Detailed Description
Statement
Reference

The nuclei of presumptive trichogen and thecogen cells of external sensory organ precursors in sv6 mutant wing imaginal discs appear smaller than that of wild-type.

Homozygotes are viable as late as the pharate adult stage. sv6/Df(4)G animals show embryonic lethality. Most homozygotes die before the wandering larva stage, with the remaining few dying as pharate adults which have profound bristle defects over the entire body surface. The microchaetae and macrochaetae of the notum often have empty sockets. Macrochaetae also occasionally show a double socket phenotype. Occasionally, the anterior dorsocentral bristles (but not the posterior dorsocentral bristles) have odd shaft-like structures with no apparent socket. The neurons of the microchaetae appear normal. A mild roughening of the eye due to fusion of the ommatidia, and occasional scarring of the lens is seen. Interacts very weakly with svspa-pol.
