      Reference

      Eggs derived from homozygous females form a syncytial blastoderm but 80-90% of the embryos fail to cellularise. Those that do cellularise show variable cellularisation defects. The embryos show a "grandchildless-knirps" phenotype; they lack polar granules and pole cells and show typical maternal kni-like abdominal segment deletions.
