The hindgut is longer than normal in homozygous embryos.
Germline clone analysis demonstrate maternal effect abnormal oogenesis. Poorly differentiated cuticle lacking denticle bands, embryo is contracted posteriorly with a large opening in the head region. Germline clones demonstrate no maternal effect.
Failure of head involution and abnormal denticle belts.
variably differentiated cuticle; complete failure of head involution with well developed head structures on exterior of the embryo. Many embryos slightly twisted with defective ventral denticle patterns.
