      Detailed Description
      Statement
      Reference

      Mst77FΔ3 homozygotes are male sterile; Mst77FΔ1/Mst77FΔ3 or Mst77FΔ2/Mst77FΔ3 transheterozygous males produce very rare progeny.

      Mst77FΔ2 homozygotes present defective spermatid individualization, as compared to controls: spermatids are in disorganized bundles, retain the individualization complexes and present defects in nuclei morphology and chromatin compaction, as compared to controls.
