Females carrying homozygous germline clones are sterile.
Homozygous clones in the adult germ cells result in defective fusomes. Germline stem cell clones show an approximately 4-fold reduction in half-life compared to control clones.
Testes from Rab1193Bi/Rab11ETo3 larvae have spermatids composed of an abnormally large Nebenkern associated with multiple nuclei.
Rab1193Bi/Rab11ETo3 brains do not exhibit polyploid mitoses.
