Adults carrying the Utxg.wt allele in a UtxΔ/UtxΔ background derived from UtxΔ/+ mothers with/without homozygous UtxΔ female germline clones can be maintained as a healthy strain.
Utxg.wt fully rescues adult mortality in UtxΔ/UtxΔ flies derived from UtxΔ/+ mothers and larval lethality in UtxΔ/UtxΔ flies derived from UtxΔ/+ mothers with homozygous UtxΔ female germline clones.
