BicDunspecified embryos develop abdominal segments in the anterior of the embryo.
BicDunspecified has embryo | anterior phenotype, suppressible by smg+t13.5
BicDunspecified has embryonic head phenotype, suppressible by smg+t13.5
BicDunspecified has embryonic thoracic segment phenotype, suppressible by smg+t13.5
BicDunspecified has phenotype, suppressible by vas[+]/vas3F
BicDunspecified has phenotype, suppressible by vas4C/vas[+]
The BicDunspecified phenotype is suppressed by smg+t13.5; wild-type head and thoracic segments are specified normally and in many cases the embryos hatch.
