Flies expressing RpS18Scer\UAS.T:Avic\GFP-EYFP.N via Scer\GAL4Act.PU in a homozygous RpS18c02853 background show no obvious external morphological phenotype but they cannot breed.
Scer\GAL4Act.PU-mediated expression of RpS18Scer\UAS.T:Avic\GFP-EYFP.N rescues the lethality of RpS18c02853 homozygotes. Rescued flies show no obvious external morphological phenotype, though they cannot breed.
