In combination with other aberrations

The wing phenotype of Dp(1;2)51b flies is suppressed by Dp(3;3)bxd110.

The increased number of thoracic bristles seen in Df(1)N-81k1 heterozygotes is rescued almost to a wild-type number by Dp(1;2)51b.

Single cells from Dp(1;1)Co/Dp(1;1)Co ; Dp(1;2)51b/Dp(1;2)51b embryos transplanted into the ventral neurogenic region of wild-type host embryos give rise to a reduced proportion of neural cells compared to wild-type controls.

Does not cover the lethality of T(1;4)wm258-21.

Dp(1;2)51b/In(1)wm51bLwmJR males have slightly mottled eyes.

Covers In(1)wm4Lrst3R. The lethality of In(1)wmJLrst3R males is covered by Dp(1;2)51b.

Does not cover Df(1)w258-45 or Df(1)w-rG. Covers In(1)wm4Lrst3R.

NOT in combination with other aberrations

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.

Other Comments

Duplication is viable and used to cover lethality of N in studies of pseudoallelism at the N locus (FBrf0014640).
