FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Cdk1Y15F.UASp.Venus, Myt1unspecified, Scer\GAL4en.PU has lethal phenotype
Cdk1Y15F.UASp.Venus, Myt1unspecified, Scer\GAL4neur-P72 has lethal phenotype
Scer\GAL4en.PU- or Scer\GAL4neur-P72-mediated expression of cdc2Y15F.Scer\UAS.P\T.T:Avic\GFP-YFP.Venus in a Myt1unspecified homozygous background, but not a Myt1unspecified/+ background, is lethal.
