Cytology
Description

Imprecise excision of the progenitor insertion, resulting in a deletion that deletes approximately 600bp at the 5' end of skpA and that extends into the first protein coding exon of Hmt4-20.

      Reference

      Hmt4-20109 mutants (Df(1)109 homozygotes carrying skpA+t4) are viable and fertile. The hatch rate of embryos is only approximately 60% that of wild type. Survival of these animals in response to exposure to hydroxyurea or methylmethanesulfonate is normal.

      Hmt4-20109 mutants (Df(1)109 homozygotes carrying skpA+t4) show a decrease in the mitotic index after γ-irradiation, similar to that seen in wild-type flies.
