ushQ41 die as pharate adults, occasionally giving adult escapers with a prominent thoracic cleft.
ushQ41/+ flies have the wildtype number of dorsocentral bristles.
Homozygous flies are viable and show a thorax cleft phenotype.
ushQ41/+; CtBPrev19/+ flies have the wildtype number of dorsocentral bristles.
