Flies carrying two copies of Dp(1;2)51b in an otherwise wild-type background have a wing phenotype indistinguishable from that of DlM1/+ heterozygotes. This phenotype is enhanced by DlM1.
Three wild type copies of N suppresses the Brd1 and Brd3 bristle multiplication phenotype.
Heterozygotes exhibit a thickened vein phenotype.
Transheterozygotes with aopA141 or aoppok-x8 exhibit enhancement of the rough eye phenotype.
Chromosome in combination with sno1 exhibits near wild type phenotype (small deltas remain, there is some thoracic hairiness and the eyes are not completely smooth): mutant phenotype is suppressed.
