hypomorphic allele - genetic evidence
Insertion of a P{XP} element in the first exon of tup, 343bp upstream of the ATG.
partially lethal - majority die | recessive
viable
visible | recessive
dorsocentral bristle | increased number
external sensory organ precursor cell | increased number
scutellar bristle | increased number
Flies homozygous for tupex4 maintain their dorsocentral bristles, but they display supernumerary scutellar bristles.
tupd03613 mutants display excess sensory organ precursors, leading to extra dorsocentral and scutellar bristles on the thorax.
tupd03613 enhances the excess scutellar bristle and thoracic cleft phenotype of ChiE flies when heterozygous.
