More severe Asx phenotype than Asx- deletion and also a more severe transformation of thoracic segments towards abdominal segments. Segmentation defects are also present: missing segments, midline denticles missing and hemisegments. Hemizygous embryos have weak head and thoracic defects and weak abdominal homeotic transformations. Heterozygous adults have a mild transformation of A4 to A5 in males.
Asx[+]/Asx15 is a suppressor of interocellar bristle phenotype of tant2
Asx15, sxc3 has abdominal segment 4 phenotype
Double heterozygotes with sxc3 show reduced viability and survivors show transformations typical of Pc-G mutants including transformation of A4 to A5. Most also show haltere to wing transformations typical of trx-G mutants.
