The frequency of variegated bithorax transformations seen in Df(3R)red-P52 heterozygotes is increased in flies also containing a copy of ash12.
ash12 is a non-suppressor of lethal phenotype of Ras85DV12.sev, sevS11.Tag:MYC
The lethality caused by sevS11.T:Hsap\MYC in combination with Ras85DV12.sev is not suppressed by ash12.
Range of lethality for transheterozygotes extends from the third larval instar for the most severe alleles to the pharate adult stage for the least severe alleles.
