Overexpression of HP1bScer\UAS.T:Avic\GFP under the control of Scer\GAL4Act.PU results in sex-biased lethality, with the lethality of males more affected than females.
HP1bUAS.GFP, Scer\GAL4Act.PU has lethal phenotype, suppressible by Su(var)205UAS.GFP, Scer\GAL4Act.PU
Overexpression of Su(var)205Scer\UAS.T:Avic\GFP under the control of Scer\GAL4Act.PU leads to a one-fold increase in male viability of HP1bScer\UAS.T:Avic\GFP flies compared to expression of HP1bScer\UAS.T:Avic\GFP alone. In females, viability increases from 54.6% to 89.8%.
