      Males testes show the development of star shaped intranuclear crystals and needle shaped cytoplasmic crystals. Males exhibit nondisjunction and chromosome condensation defects.

      (Bozzetti et al., 1995)

      Heterozygotes with cry1Y are sterile. In a search for viable deletions of Ste neither X irradiation of males, to produce sperm from gonial cells where part or all of Ste locus is removed, or Δ2-3 treatment of males, to produce deletions by imprecise excision of the insert, gave progeny when mated to virgin females. Mating to compound X cry1Y females gave 2 fertile sons, one was lost the second carried Su(Ste)+ from an exchange with the other Ste+ revertant. Lethals were recovered using Δ2-3 treatment without selecting for viability.

      High resolution in situ hybridisation with a P-element probe reveals the R301.2 chromsome has two insertions, one at 12D and the other colocalises with Ste sequences at 12E1-12E2.

      (Palumbo et al., 1994)

      'X,301.2 Ste' chromosome carries 300 copies of Ste.
