Insertion of a P element of 0.6kb length at coordinate +25.
Homozygous adults show a reduced response to propionic acid, ethyl butyrate, 2-butanone and ethyl acetate in an electroantennogram assay compared to control flies. The response to butanol, 1-octanol, benzaldehyde, butyl acetate and 2-heptanone in this assay is not significantly different from the response of control flies to these odorants. Mutant flies have fewer antennal neurons that are sensitive to ethyl butyrate than control flies.
Homozygotes show increased sensitivity to trichloroethylene and halothane, but not to chloroform in an inebriometer assay (an assay of geotactic and postural behaviour) compared to wild-type flies.
Ether induced leg shaking and electrophysiological defect characteristic of eag mutations.
Reverts to wild type under dysgenic conditions, with loss of P element from eag region.
