Deletion of 646bp and an insertion of 29bp at the same site within the 2.2dis element, located 2.5kb upstream from the start of transcription.
Small deletion in the PstI HaeIII fragment that removes or alters the PstI site, results in deletion of a transcriptional silencer element.
AATTTATTTATTAACTGAATAAATTATTT
Deletion of 646bp and an insertion of 29bp (AATTTATTTATTAACTGAATAAATTATTT) at the same site.
Does not affect embryonic development but causes an adult phenotype, vein defects in the posterior compartment of the wing.
Coordinate mutant.
Wing vein interruption. Homozygous viable.
Wing phenotype is enhanced by enEnci at 18oC.
Hochman, July 1957.
Strength of ci alleles showing a ci phenotype in combination with enEnci can be ordered: ci1 < ci36 < ci57 << ciW.
