A GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain) has been inserted at the start codon within exon 2 of dsx. This results in the hemidriver being expressed under the control of endogenous dsx sequences, along with deletion of exon 2.
dsxGAL4(DBD)::Zip-/dsxf00683-d07058 adult males have a similar number of doublesex TN1A neurons to dsxGAL4(DBD)::Zip-/+ controls; these neurons have a similar gross morphology and similar anterior arbor volume, but significantly reduced posterior arbor volume, compared to dsxGAL4(DBD)::Zip-/+ controls.
