The FRT cassette has been excised, juxtaposing 5XQE enhancer and vg coding sequences.
lethal | germline clone | larval stage
lethal | larval stage | somatic clone
lethal | pupal stage | somatic clone
Animals expressing vg5XQE.cZb (generated by germ-line excision of the Scer\FRT cassette in the vgScer\FRT.CD2.5XQE progenitor allele) show larval lethality.
vg5XQE.cZb clones induced in first instar larvae result in late larval or pupal lethality.
