A small proportion of somatic clones of Df(1)G1 in the wing disc appear to undergo apoptosis when the Roc1bScer\UAS.cDb transgene is expressed under the control of Scer\GAL4en-e16E.
Scer\GAL4en-e16E/Roc1bUAS.cDb partially rescues Df(1)G1
Expression of Roc1bScer\UAS.cDb under the control of Scer\GAL4en-e16E increases the size of Df(1)G1 somatic clones in the wing disc, but does not elevate these to the full size of wild-type cells. This partial rescue is fully penetrant.
