female sterile (with gwlSr3), with Scer\GAL4Act.PU, gwlNLSmut.UASp.Tag:MYC
viable (with gwlSr3), with Scer\GAL4Act.PU, gwlNLSmut.UASp.Tag:MYC
Scer\GAL4Act.PU-mediated expression of gwlNLSmut.Scer\UAS.P\T.T:Hsap\MYC in a gwlSr3/gwlSr6 mutants background results in viable but female sterile flies. Ovaries are completely lacking.
gwlSr6 homozygotes die as pupae (although this is believed to reflect a second lethal on its chromosome).
gwlSr6 mutants are sterile in both males and females.
gwlSr3/gwl6a mutants exhibit mitotic defects, leading to an increase in the mitotic index with more cells in anaphase. Mutant neuroblasts show a high frequency of defective chromatin condensation. Some regions of chromatin appear undercondensed and other regions are overcondensed. In some cells the chromosomes are uniformly overcondensed, suggesting a lengthy pre-anaphase delay.
gwlSr3/gwlSr6 adults eclose (after a delay), with variably rough eyes, eroded wing margins, missing bristles and strongly reduced gonads, though viability is reduced.
gwlSr6/Df(3L)gwl3b mutants die predominantly in the pupal stage, and the rare escaper adults have rough eyes, ragged wings, cuticle defects, missing bristles, and are sterile.
gwl3a/gwlSr6 mutants produce a gwlSr3 phenotype, i.e female fertility is restored.
gwl2/gwlSr6 mutants produce a gwlSr3 phenotype, i.e female fertility is restored.
gwl6a/gwlSr6 mutants produce a gwlSr3 phenotype, i.e female fertility is restored.
gwlSr6/gwlSr3 is rescued by Scer\GAL4Act.PU/gwlUASp.Tag:MYC
gwlSr6/gwlSr3 is rescued by Scer\GAL4Act5C.PU/gwlL.UASp
gwlSr6/gwlSr3 is rescued by Scer\GAL4Act5C.PU/gwlK97M.UASp

gwlSr6/gwlSr3 is partially rescued by gwlNLSmut.UASp.Tag:MYC/Scer\GAL4Act.PU

Scer\GAL4Act.PU-mediated expression of gwlScer\UAS.P\T.T:Hsap\MYC completely rescues the lethality of gwlSr3/gwlSr6 mutants.
Scer\GAL4Act.PU-mediated expression of gwlNLSmut.Scer\UAS.P\T.T:Hsap\MYC incompletely rescues the lethality of gwlSr3/gwlSr6 mutants.
Scer\GAL4Act.PU-mediated expression of gwlScer\UAS.P\T.T:SV40\nls2.T:Hsap\MYC incompletely rescues the lethality of gwlSr3/gwlSr6 mutants.
Based on viability, the following gwl alleles can be ranked from strongest to weakest as follows: gwlSr3 > gwlSr3/Df(3L)gwl3b > gwlSr6 > gwlSr6/Df(3L)gwl3b> gwlSr3/gwlSr6 > gwlSr18/Df(3L)gwl3b.
