Additional Comments
Genetic Interactions
Statement
Reference

Addition of Chc+t14.3 to a auxD128/auxK47 background increases the eclosion frequency of adults markedly. The mutant eye phenotype of those rescued animals is suppressed somewhat (from 8% to 28% wild-type ommatidia).

auxD128/auxK47 mutant flies carrying both Chc+t14.3 and lqf+t16240.T:Avic\GFP exhibit remarkably normal-appearing eyes (97% wild-type ommatidia). However, no increase in viability is seen in these flies above the level observed with lqf+t16240.T:Avic\GFP alone.

Chc+t14.3 completely suppresses the mutant wing phenotype of auxD128/auxK47 flies and significantly suppresses the mutant facet phenotype of auxD128/auxK47 flies.
